gourish	Hello, Add the line MAXIMUM NUMBER OF BOUNDARIES = 30 in your steering_1.cas file, however the value 30 should be replaced by the number of boundaries which are there in BC_1.cli file. With Best Regards, Gourish

sir i am putting link for the mesh file below. Can someone help me the problem with the mesh. while running simulation it shows this. whats the error.

READ_MESH_INFO: TITLE= newSelafin
NUMBER OF ELEMENTS: 624930
NUMBER OF POINTS: 320676

FORMAT NOT INDICATED IN TITLE

MXPTEL (BIEF) : MAXIMUM NUMBER OF ELEMENTS AROUND A POINT: 57
MAXIMUM NUMBER OF POINTS AROUND A POINT: 58
CORRXY (BIEF):NO MODIFICATION OF COORDINATES

MESH: MESH ALLOCATED

i indicated the format .slf in the title. please please help

Hi
I didn't had a look to your mesh (lack of time) but it's clear you have to work on it...

The simple mention of 57 elements around one point clearly indicate a problem somewhere...
just to try to explain in a simple way, it means that you had 57 triangles linked to one node which means each triangle had an angle of 6° but probably some of those triangles had a smaller angle. This will lead you to some numerical problems with the consequence of a very small time step.

Hope this helps

Christophe

riadh	Hello I tried the mesh and everything looks fine ! there are 103 overconstrained elements but the remaining criteria seem to be good. So you can go on with your simulation with my kind regards Riadh
