Article What is the commonly used contact type in stamping analysis?
In LSDYNA, there are many choices for contact. What is the commonly used contact type in stamping analysis?
Article What is FLD?
Article What can I do if the mesh for the last state was not written to the d3plot after restarting from d3dumpxx?
I performed springback analysis using the seamless method, but no converged solution was obtained. Then I wrote a small input deck and restarted the calculation from d3dumpxx. From the message file, the converged solution was obtained, but when I tried to use Taurus to display it, the mesh for the last stage was not written to the d3plot file. Is there a way to avoid this?
Article What can I do if the direction of the pressure is not reasonable after the mesh had been refined adaptively?
When I used adaptive mesh in hydro forming simulation, there was no problem in the initial stage. However, I found that the direction of the pressure wasn’t reasonable after the mesh had been refined adaptively. What was the problem and how can it be fixed?
Article What are the differences between smooth and non-smooth trimming?
There are two methods in trimming, i.e. smooth and non-smooth trimming. In smooth trimming, the boundary element will be cut exactly along the trimming curve; while in non-smooth trimming, the boundary element can be either kept or removed from the model and it will not be cut in half. What is the advantage of each method?
Article There is no load applied to the blank when I used *LOAD_MASK. What might be the problem?
When I used *LOAD_MASK for hydro-forming analysis, first I have no problem in applying the load, but the load is in the wrong direction. I used negative value for the load curve to reverse the load direction. However, there was no load applied to the blank anymore. What might be the problem?
Article There are several non-linear solvers for implicit analysis - which one is better?
