contact problem in Geostatic step.
contact problem in Geostatic step.
(OP)
Hello There,
I am running a geostatic step for my model, the model is composed of 3 layers Roof, coal, and floor. the coal layer is sandwitched between the roof and the floor. When i run the geostatic step, i found that the roof and the floor penetrate the coal layer completely and they touches each other. This is strange.
I fix the bottom of the model in X, Y and Z, the model is X-Symmetry.
the units used in the model is lb, ft. I think nothing is wrong with the units.
this is the input file, please help me.
Thank you.
