Hi Domado,

NEGATIVE VOLUME or ZERO VOLUME is terminating the run. This error happens when solid elements are very deformed and their characteristic length goes to 0. For large strain formulation the time step of an element goes to 0 when the element is compressed. In RADIOSS Starter input file (Runname_0000.rad), use Ismstr =2 in the solid property and when using this formulation, set Isolid =14 and try running the simulation.

Thanks George.

How to use Ismstr =2 in the solid property and set Isolid =14 ?

Please show me how to use and set.

Altair Forum User

Hi Domado,

Click on the solid properties in the model browser and edit Ismstr and Isolid in the entity editor. Please see the attached image.

This message appears. Should I change the values of all properties?

And this file increases kinetic energy.
