'Plate_hole' simulation project by bloodyzohair


#1

I created a new simulation project called 'Plate_hole':

A non linear analysis on a plate with a hole.


More of my public projects can be found here.

Hi @stadlerj ,

I wanted your inputs on the simulation.

Specifically on “Simulation 1 2 2” and its solution fields.

Thanks,

Zohair

Hi @bloodyzohair,

yes you are right! I made an error in the .csv file. For the different material model, the result field is completely different.
Thanks for the input! Gonna change it right away.

Actually I checked my project and everything seems fine. I thought you imported the first run from my project and setup the second one accordingly.

The solution field in “Simulation 1 2 2” looks so different in comparison to my simulation because of your choice of elements. You are using a coarse mesh with linear tetrahedrons. This results in an unrealistic solution field. Try either to refine the mesh, or consider using quadratic elements.

Hi @stadlerj ,

Thanks for your insight. :slight_smile:

Yes, you are right. The solution field is unrealistic. The von Mises stress actually has a negative value, even though I have setup the simulation with your simulation as a reference except the mesh.

I will remesh the geometry and will compare the solution fields.

Thanks

Zohair

Hi @bloodyzohair,

the negative value is correct, since it is not the normal von Mises stress, but the signed von Mises stress. But I guess you already figured it out yourself ;)!

All the best from Munich
