We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Reno,

I can confirm my mesh is watertight and conformal with the solid body.

I have just tried to run it with Tethaedrons (triangles) and it seems that it has meshed successfully! However, the running time for the ICFD-only is still very low (2e-6s steps every 3min for a 80,000 elements on the surface mesh). Can you confirm this run time should be expected for an engineering-prepared workstation? Maybe there is still something wrong?

On the other hand, my LS-Dyna version is R11.2. It is good to know that future versions can locate the error, but unfortunately, license is provided by my university and I am afraid I can't ask for a newer version.

In any case, are these runtimes common?

Now that at least I can run the model, I can keep working on it. Thank you very much for your time and help in this, it is very much apreciated!

I hope you have a great day.
Arnau
