Radioss analysis remaining time is so long.

labex

Description: I am trying to solve a 3 point bending model on Radioss and Hypermesh. I modeled all the parts and set all the parameters. However, the remaining time of the analysis is so long like 20+days. I have to modeled the parts 3D to obtain clear results. I think the analysis lasts shorter. Can you help me? I have attached my ".hm" file. I cannot attached rad file because it is more than 100 mb.

from the .out files you would be able to check the critical timestep.

As it is a explicit based run, it is defined by the timestep. You model has really small elem size, so naturally timestep needs to be small to capture well.

You can see in HM as estimation on the minimum timestep at 7.35e-8.

To run a total of 0.1s it takes some time.

So in order to speed up, you can re-think on your mesh size, try to use more core`s to solve it, or depending if this is a quasi-static test, you could intentionally allow mass scaling, increasing artificially the timestep.
