[GiDlist] Units file

[My VDI Freemail]

Could someone help me on the input data for the units file (problemtype_name.uni) with regard to the definition for a materials density?
Is there any specific parameter for defining the DENSITY as it is done for example for the STRENGTH or PRESSURE?
This would be helpful for the complete characterization of a material within GiD.

Thanks for your help.

Hello Ruediger, you can define your own .uni file. Here I send you and
example. The one provided with GiD is not a good example and it will be
changed. There are also two links regarding units systems. You should
try version 7.2 of GiD. Although there is a known bug when writting
TEMPERATURE in .bas file. That bug is fixed and ready to be release in
next beta.

This is the unit file example, best regards, Jorge Suit.
