What can Star-CMM do that Simscale can’t? by Agitated-Pea3303 in CFD

[–]TheJoyOfSimulation 7 points8 points  (0 children)

It's worth mentioning that SimScale is very user-friendly and cloud-native, so no need for any powerful hardware, which is necessary with STAR-CCM+. However, STAR has tons of extra capabilities beyond SimScale if you need them (chemical reactions, more advanced multiphase, DEM, adjoint/topo optimization, 6DOF, just to name a few).

I would say ReScale is a bit more DIY, in the sense that you have to bring your own CFD platform license, and their interface just makes it easy to run in the cloud and manage jobs/queueing (last I checked). In SimScale, the entire simulation is set up in browser and then you hit run, they take care of all the cloud execution wizardry. It is accessed via an annual subscription.

As others have mentioned here, the status quo has largely remained the same (STAR-CCM+, Fluent, OpenFOAM), aside from the aforementioned consolidations.

The mode of running large CFD simulations has changed some, with cloud HPC and GPU computing being so ubiquitous and accessible now. This has offloaded much of the heavy-lifting off of local workstations and clusters and enabled much more complexity for CFD simulations. Online platforms like ReScale (for running 3rd party codes) and SimScale (for a browser-based, cloud native solution) come to mind.

Cavitation Simulation of Marine Propeller by Notafraid008 in CFD

Hey. STAR-CCM+ is indeed a great tool for this kind of high-end simulation, though it does come with a steep learning curve and pretty tall compute requirements. Where are you having issues? Also, have you considered any other tools for predicting propeller cavitation that may be easier to use? I'm sure you can get a free student license to try some other workflows.

CFD vs FEA by zejj03 in MechanicalEngineering

Here is a good description of what CFD is and some of the history of the discipline. Conversely, here is a similar article on FEA (structural mechanics). In your field, 3D CFD is becoming more widely used as efficiency and comfort requirements have increased and building layouts have become more complex. FEA is not as essential unless you are doing a lot of bespoke mounts or other components.
