Thanks Victor, I have tried to modify my code so it has the step definitions similar to yours. However, I am still having problems with getting the right step value. In my attached .inp file, I tried to have a 0.9 time delay so I can obtain results …

Thanks Victor, I tried to follow your structure of declaring the step conditions. However when I ran the simulation, it seemed like the first step condition was only simulating at the total step 1.0 and the second step condition was running the simu…

Thanks very much for your input Victor. Do you mean something in the form below? *Step *Boundary *Static,Direct 0.8 *End Step *Step *Boundary *Static,Direct 0.1,0.9 *End Step

Hi there, Regarding the step settings for Calculix, Is anyone aware of specifying the steps for simulation? For example: If I have 1 as the total step time, I would like to only run the simulation between step 0.8 and step 0.9 with a step inc…

Thank you for your suggestion Sergio! I will give that a try for now. However, do you know the reason for not being able to simply just apply a force load in place of the displacement? Previously I have tried to apply forces ranging from -1E-11N to …

Thanks Victor, that has been giving me much better results! I am currently trying switch to a force load instead of using the displacement as a load. For my analysis, I need to be able to vary the force instead of the displacement. I have tried to…

Hi Victor, I have tried to increase my "slope of pressure-overclosure curve k" to 20000Gpa. I have also tried to use smaller element sizes for the laminate and a concentric cylinder for the top roller, but the contacts are still penetrating. Any ot…

Hi Victor, That makes sense now. I have tried the other method you mentioned which was to use a displacement instead of the force as a load while still keeping the rollers. I have also switched the material of the laminate just to simplify the mod…

Also, is the transformation of the local axis not allowed in the non linear static 3D analysis? When I set my U axis as 1,0,0 and V axis as 0,1,0 in a static 3D analysis it is allowed. However, when I switch to the non linear analysis the component …

Hi Victor, I have tried to run the revised model that you have provided but the ccx solver is exited with an error message: "*ERROR: too many cutbacks best solution and residuals are in the frd file" Did you get the same error message when you tr…

Hi Victor, Thank you very much for letting me know that the non linear still works with orthotropic. I have tried to recreate a three point bending test with pin rollers at the top and at the bottom as mentioned before. However, I have not been suc…

Hi Victor, I am trying to model the three point bending test using nonlinear analysis and CCX contact as you have mentioned. However, I could not select the orthotropic properties when trying to change the material properties? Is there anyway to in…

Thank you very much for your help Victor, that made it much easier to understand.

Hey Victor, Thanks for explaining that to me. I will take into consideration what you have just said. For now, I think I will be using the displacement constraints as you have mentioned. Just another question, when trying to model a composite lam…

Hey there, I am currently working on a three point bend test for a composite laminate plate. Does anyone know if it would be possible to model two actual cylinder bars instead of the displacement constraints? If so, what would be the constraints fo…
