ANSYS Workbench加载生成热载荷internal heat generation rate的问题

模型中施加了内部生热载荷Internal Heat Generation之后就无法计算，显示为“An internal solution magnitude limit was exceeded. Please check your Environment for inappropriate load balues or insufficient supports. Also check that your mesh has more than 1 element in at last 2 directions if solid brick elements are present.” 模型中各个体的接触都检查过没有问题，并且删掉内部生成热载荷就可以计算。有没有人遇到过类似的情况，应该怎么解决呢。感激不尽！
