我用Ansys/LS-DYNA计算碰撞问题,并引入了热固耦合,并在*CONTROL_THERMAL_TIMESTEP关键字中把最大温度允许值设为50000℃,按理这一值是肯定不会被超过的,但计算时会超过这一值,从而提示出错:*** Error - the minimum time step has been reached and the maximum temperature change is greater than specified
solution time 7.4282E-09
time step size 1.0000E-10
node 300
temperature change 8.4465E+04
max allowed temperature change 5.0000E+04
suggestion - increase max allowed temperature change
decrease minimum time step
