Hi
I guess you are using ICEM for meshing. If you are using CFX-meshing, i might be able to help you. Just let me know. Regards, Aplus |

Hi
ANSYS has two meshing software for CFX: 1- Advanced meshing which is basically ICEM 2- CFX meshing I am using CFX meshing and I got similar message as yours with prism with zero elements. As I remembered when I put the meshing setting, it did not give me errors (committed) but when I ran the volume or surface meshing it gave error. The reason was due to the one of the setting which was not accepted by the meshing code. Check if all mesh options are OK. I mean do not have confliction with the meshing setting. If it is OK, try to suppress one setting a time and see if the error disappear…. Regards Aplus |

Thanks again Aplus
I do not have that much relating to meshing and meshing settings BUT I always use VSWEEP command in ANSYS with no argument (I like defaults) yours abdulaziz |
