I checked my model and you are right. The nodes with temperature boundary conditions were not in contact with the tool. Hence there was continuous increase in the tool. I have rectified the problem.
Thank you for your help!
Thank you for the reply.
My thermal boundary is limited to the tool having temperature of 20°C and the workpiece with 1050°C. The tool material is defined by MAT_RIGID with THERMAL_ISOTROPIC property. There is Heat Transfer Conductance defined at tool-workpiece contact. Is there any other...
I am simulating a hot forging process in LS-Dyna. A tool is contacting a hot workpiece for 2 sec every 10 sec (--0 sec--contact--2 sec--no contact---10 sec--) in a factory. Since this is a continuous process, the tool should, at some point, attain steady temperature. I have tried to recreate it...
