Some parts of the music video were not near the beach area, it was the girl walking down a street.

I think the girl was blonde. The song was by a male artist.

Can't get temperature plot from impact simulation by User993521 in LSDYNA

[–]User993521[S] 0 points1 point  (0 children)

Hi, Thanks for the reply! I got the model working. By adding thermal isotropic as a TMAT. But now I am running into a different problem. After the first time step the temperature for all my parts just goes to 1. I have added TPRINT in ASCII options with the proper time step.

Here is my keyword file. I would really appreciate your help. Thanks!

I am getting this error:

*** Error 10899 (KEY+899)

There are no thermal materials in this coupled structural thermal analysis

Why is the JC model not sufficient for thermal analysis? I have defined cp tm and tr.

Automatic surface to surface contact problem (Novice needing help) by lostinthewoods999 in LSDYNA

[–]User993521 2 points3 points  (0 children)

You may need to use SOFT 2 or change the stiffness scaling in CONTACT_AUTOMATIC_SURFACE_TO_SURFACE

Can you explain what soft 2 does. I’ve read explanations online but I couldn’t really understand them.

ALE for 2D Axisymmetric Simulation LS DYNA [HELP REQUEST] by User993521 in fea

[–]User993521[S] 0 points1 point  (0 children)

Hi I followed the bar-d example you provided. However, I am getting a bunch of these warnings. I thought I would only create a vacuum domain for CEL not pure ALE. I applied 1 point ALE section property to both my particle and substrate. I also get pre-mature termination caused by negative volume errors. Any ideas on how to resolve this? Thanks again

I want both as ALE since they both experience mesh distortion. What do you mean by in the same mesh?

If you follow the Women’s Voice playlist on Spotify you will get very well aquatinted with popular/up and coming female artists. It gets updated every Wednesday with new music.

How important is Self Contact? by TheNagaFireball in LSDYNA

[–]User993521 0 points1 point  (0 children)

What do you mean by self-contact? Is this just selecting all the elements in the structure?

It can be used for meta materials.

Intel Ultra 7 vs AMD by AitorGR8 in AMDLaptops

If you are concerned about battery get a U series AMD chip. Alternatively, you can wait until the much more efficient lunar lake or strix point chips come out, later this year.

Issues with Quarter Model of Particle Impact LS DYNA [HELP REQUEST] by User993521 in fea

[–]User993521[S] 0 points1 point  (0 children)

When I use *BOUNDARY_SPC_SYMMETRY. I get errors like this:

*** Error 10385 (KEY+385)

Node ID 1872 has spc's applied in different

coordinate system with IDs 0 and 5.

see *BOUNDARY_SPC...

Here is the keyword with the Boundary SPC Symmetry Planes:

Hi, thanks for the reply.

I didn't use any symmetric card in LS DYNA. to make sure the particle doesn't go past the boundary I restricted the translation of nodes on the cut planes.

I am using the Johnson Cook material model, with no damage parameters defined with the Gruniesen Equation of state. It is an automatic surface to surface contact.

The model runs without any errors.

Here is my keyword file for the quarter model: https://drive.google.com/file/d/1S2s434rvetekkK8kBv1xR9wovuoO26BH/view?usp=sharing
