小球在溶剂中的溶解

请教一个问题啊,我是模拟一颗小球在溶剂中的溶解,随着溶解溶剂中的温度场和浓度场都会变化,在溶剂中就会有温度梯度和浓度梯度,而球的体积也在减小,这个用ANSYS怎么解决呢?

CFX.小球为粘度很大的液体,加化学反应热.

看了一段时间的资料,发现可能这样能解出来,我再研究研究吧,谢谢啊

This is a multiphysics problem. I don't know if the ANSYS has the models for your diffusion and reaction problems. But worst case, you can solve the these problem in other FEM software (or write your own FEM code) and provide the heat generation for ANSYS for next step simulation and the temperature field will feeback to your other software for reaction and diffusion simulation.

Or you can use FEMLAB if you have the differential equations for all DOEs.
