ICEM 13_Coordinates change after reading geometry from Solidworks; any ideas?
 
Dear all,

I am trying to model the gas circuit of a Wankel rotor in Fluent and I'm facing a problem which originates- I think- when I import the soliworks file to ICEM 13 (through WB readers etc)

So what happens is that min and max (x, y) in solidworks are different from those in ICEM and then fluent. It's not just an offset which I can translate back to where I want because the offset in the positive x or y axis is different from that in the negative axes

Example,
Solidworks: min (-0.095, -0.073) max (0.095, 0.073)

ICEM/ Fluen: min (-0.0953278, -0.072578) max (0.0951, 0.074656)

I used random numbers but close

It's important 'cause I have a CG motion UDF with the eccentricity etc and I need to get the coordinates spot on,,

I would appreciate any ideas


Best,
Thanos
