Hi Shi,

Do you have any error/out messages printed somewhere? It is not easy to say exactly what is going on based on what you shared. One thing I can recommend is to lower your fine meshes, for example nkf1 = 10, nkf2 = 10 and nqf1 = 5, nqf2 = 5 and see if you could run or not.

Happy EPWing,
Hari

Thanks a lot,i run again ,it works
