CAN YOU PLEASE EXPLAIN IN DETAIL WHY IM GETTING THIS ERROR
Hi,
ERROR # 70
i believe the error message says it clearly that you are running some thermal stress analysis in your model, and you have not provided the thermal expansion coefficients (alpha / A) in your material card.
As you want to compute thermal stresses, these will be generated from thermal loads, and these loads will cause your parts to expand or shrink due to thermal expansion effects. Thus it is mandatory that you define thermal expansion coefficients.
