Hi Armin,  

 

Thank you again for your prompt feedback, I have applied your advice and we are still with a calculation around 48h. 

We know it’s not a simple geometry but I think Ansys is able to work with more complicated models and I think we forgot something to complete our calculation. 

Our fence is like that :  






And we want to compare our model with real life tests we have realized. To explain quickly, we pulled on a beam (symbolized here by the cube) and measured the deformation as a function of the force applied. We want to validate a model who is giving close results to our tests. 

And during our real test, it took us around 10s to remove the ties but if we make a model of 10s we have a time of resolution of 400h. 

Do you think it’s possible to do it with Dynamics Explicit ? and how ? Is LS-DYNA a better solver for those long calculations (end time > 1s) but with highly nonlinear deformations ?

Thank you for your help.

Best regards
