<?xml version="1.0" encoding="UTF-8"?>2015-12-29_15-34-31.thumb.png.4b19060faf

 

I have activated the ENG/DT/BRICK CST as well and set Tscale and T min as follwing (are the valuses for Tscale and T min correct?) but I still get the same error. Would you please check my attached model and see what is wrong? Thanks a lot in advance

Thanks for your reply Prakash. I am using Radioss block 120 and I am using Hexa elements. So I read the posts you have refered before but they didn't help me. I have used M36 Plas TAB plastic and I have used P14 SOLID as card image. What should be the values for

ISOLID ?

Ismstr ?

Icpre ?

 

I have activated DT/Brick/CST in control card what shoulbe the values for Tscale and Tmin

 

is it ok to use hexa elements here or do I have to switch to tetra. (As I read before tetra elements are stiffer than hexa. Does it help to switch to tetra?)

 

Thanks for your help
