When you have problem in the simulation with Dynaform, you could take a look at the file named "message", which
contains the information during computation. And the best way to do the simulations with Dynaform to to learn
LS-DYNA directly since Dynaform is only a kind of preprocessor. As a matter of fact, open the file with *.dyn which is
created by Dynaform, check all the keywords and the parameters, you could have a better understand of your
model. That's how I learn Dynaform and how I use it.
