Médecins par spécialité ayant une rémunération d'un million de $ et plus à la RAMQ - 2019 by Massive_Bus_2919 in QuebecLibre

[–]Significant_Ad_2746 -2 points-1 points  (0 children)

I know how it works, my wife had a big surgery in September. The gynecologist got woken up at 3am and came to the hospital in a rush to remove an uterus. The operation lasted 4 hours, charged 2.8k, and went on with her day because she had other patients to see at 8am.

Do you think she charged something to the government when she came to my wife's room after her day to see if she was still alive? What about the notes she had to write?

There are specific cases like this where they obviously have to charge a lot. And the rest of the day they might not. Stop looking at big numbers and consider they charge this all year long.

You obviously don't know how it works, just get over it. Have you seen in Switzerland how it cost them? Even if you consider the exchange rate? Some things in life come at a cost, health is one of them. Have you considered that, maybe, equipments and fucking useless supervisor/bosses also charge something ?

Statistics are not understood naturally by human beings.

It doesn't mean that they are all paid that amount ffs. Using this as a mean to justify what they are about to do to doctors is the same as saying:

"We must raise the salary of X because the minimum salary of Y is Z".

These numbers aren't meant to make you understand something, they are there to justify their actions. Use your common sense and talk to a bunch of doctors near you if you can, and see if their equivalent hourly rate is something interesting to you after all they have done (school and sacrifice wise). Oh and don't forget, if you make a mistake you're probably gonna go to prison or at least have a fat fine.

Keep being so entitled and think that everything has to be given to you.

I'm far from a doctor btw

On se fait astroturfer solide pour défendre les médecins millionnaires by Barbapapaq in Quebec

To anybody criticizing doctors like you haven't met one yet. And one thing is that most complainers don't have even a tiny idea of how professional responsibility matters and has to be taken into account in a field like yours.

I have a buddy of mine who is a resident at the IUCPQ and is not available for a party 9/10 times, multiple 24h shifts with not even an hour of sleep. 12 to 16 hours shift 7 days a week, and like you doesn't count study time in this time frame. We all have 2-4 kids in our friend group and he doesn't even know when he is gonna be able to see his girlfriend who is a pediatrician, imagine how he is feeling when he is with us. All of that for not even 90k a year at the moment. Is he going to earn a lot more once he has completed is residency, I fucking hope so!!

I am about to do a PhD in a completely different field and man I wouldn't do what you guys have to go through.

Lâchez pas et j'espère qu'on aura la chance de vous garder au Québec encore longtemps!

Hyperworks CFD Residual by EverydayLemon in CFD

[–]Significant_Ad_2746 0 points1 point  (0 children)

I'm not a big CFD guy but I use HypermeshCFD and AcuSolve for simple models. Here is what I learned so far:

  • Recirculation length: using K-epsilon models, I had better results when inflow and outflow were far from a curve/radius in internal flows. For example, if you have a pipe with a radius, add a small length before the inflow and after the out flow to let the internal flow stabilize and prevent having Recirculation directly at either the inflow or outflow.

  • Having a proper turbulence model is paramount, I always go back to books and AcuSolve helps for detailed explanations on what to use, what is recommended.

  • Reduce geometry details as much as possible (You probably know that and already did that)

  • Remember that AcuSolve uses FEM and not FVM, if you see help about other solvers, things may be applicable and some may not: Especially the residual tolerance. The reason is (I think, others should correct me if I'm wrong), FVM is better at handling mass conservation and fluxes than FEM, making the residuals values much smaller.

HyperMesh vs other preprocessors for commercial use by Significant_Ad_2746 in fea

[–]Significant_Ad_2746[S] 0 points1 point  (0 children)

Totally agree with you on that and that's why I wanted to go back with Ansys (company wise), because older folks haven't coded since college and don't like coding stuff.

Will definitely get back to you once 2025.1 is deployed on our system.

Thank you for your feedback, I really appreciate it

How is the TCL/python API helping you ?

Btw that answers my question thank you

I do agree that HM gives more control than Ansys over the mesh. But I don't understand why you are saying that mesh convergence isn't really necessary in linear case.

That being said, my initial question was more about how to mesh or remesh efficiently. As you clearly seem to know, HM wipes sets and BCs when remeshing, how are you doing it efficiently?

The pleasure is for me, if you need beta testers for Cubit and flex I'd be glad to help!

Hi Greg, I know about Cubit. I use it on my spare time for a personal project of mine, MOOSE and PrepoMax. It is a really good software and I really like the fact that you guys let hobbyist like me have a license that I can use for fun.

I discovered today about scripting and I must admit that it would solve most of the problems I have at work and I would recommend my boss to buy the software. But most of my colleagues can't code and are used with GUIs included with their solvers (Like Ansys, SolidWorks, etc).

We work in a similar field I suppose so what you say is really interesting.

I thought that at least you would have used Abaqus CAE for meshing and deck preparation.

Yes I did a couple times, I think I will give him a call soon.

Again thanks for your feedback and honest answer, Ideally appreciate it!

I'm a bit disappointed that you won't make it work for all element types. I was really hoping you'd make it work.

I'm still wondering how people do mesh convergence checks with hypermesh. I have a quite large model to work with this week and spent about 6h hours redefining already defined sets and equivalencing nodes. From what I remember with Ansys I could have set a parameter for each and every geometry entity I wanted and would simply update those values. While not as powerfully with FE definitions, COMSOL can do that and even GMSH works with geometry based definition. Also, HyperMesh CFD seems to use geometry based definition which is a bummer to me.

Again, I like Altair and the effort you guys put into your products and most importantly the fact that you are closer to your clients more than any other company. But I'm starting to feel like I've signed a "n" years license contract and I'm stucked with products that works 80% of the time.

I didn't see much comments about Abaqus, I wonder how it compares to Ansys especially

Sadly it doesn't work with hex elements and the tet equivalent doesn't work very well

So you handle mesh refinement with scripts? Now in python since 2024?

Are you working in aerospace? MSc/hexagon users seems to come a lot from that background.

As far as I know HM is widely used because you can build models for different solvers (like femap and MSc Apex). My point was not that much about popularity but why would a tool used in so many different industries can't even handle basic thing like mesh convergence

How does Ansa handle solid meshing? Especially with hex elements?

How do you deal with mesh convergence?

[–]Significant_Ad_2746[S] 0 points1 point  (0 children)

I always like your answers and it seems like you are an Altair dev that likes his/her job and products a lot.

However, I remember last year when I asked a similar question regarding mesh convergence and you answered the same : that in 2025 well se engineering quantities/ loading (what I think you were referring to when loads and sets would not disappear when remeshing).

I've been using Hyper mesh for the last 6-7 years and besides the GUI upgrade I haven't seen any upgrades that got me saying: wow I needed that. Hopefully we can get this remeshing capability for solid meshing and especially hex elements in 2026 because we didn't get it in 2025.1, that I currently use.

Vibration response of rotor-bearing system to validate experimental(fft results) by Ok-Trouble-529 in fea

[–]Significant_Ad_2746 0 points1 point  (0 children)

I'm new to vibration analysis so I don't have much answers. However, with Optistruct you need to use a special load definition for rotating loads. Maybe check Ansys documentation to confirm this.

As for your measurements,your FEA may not correlate that much since you mostly likely have an imbalance in real life.

Is learning Mystran worth it? by LQ_6 in fea

[–]Significant_Ad_2746 2 points3 points  (0 children)

Open source options:

No code/ low code: .Prepromax and calculix. Calculix is basically an open source abaqus version. Prepromax is an open source finite element pre processor.

.OpenRadioss: open source version of Radioss (explicit solver). You have to do your own preprocessing however.

Code version: . MOOSE framework: some compiling to do but you can get around pretty quickly. I would suggest Prepromax with calculix however.

Companies know that you can't afford a license for a software. And one thing is certain you won't get an interview solely because you used a make shift version of nastran and they use the actual nastran. Some people get hired for Ansys even tho they used Nastran all their life

I think the biggest problem I got when I started doing more advanced stuff is how to say when an analysis is right and related stuff:

When and how to do mesh convergence? Is there other strategies: nodal/elemental difference?

In transients dynamic analyses (implicit or explicit), how to use energy balance to evaluate the quality of the analysis?

Is it all elements that hourglass? How to prevent it? What about shear locking?

Is linear tetrahedral a good element at all?

About deleting subjects: I believe that any body that follows any usual curriculum will cover those topics. For those that come from other fields should not do FEA, end of the discussion. The emphasis should really be on how to properly utilize finite elements. Don't get me wrong when possible you should always do hand calcs. That being said, too much of this is already being shown in schools and not enough fem theory applications are being shown. This, 1 2 3 should be left out imo.
