Summary: Geometric tolerance value for the Boolean operations performed while transferring a geometric model into Autodesk® CFD.
Flag:
AsmCoinTol A
A is the tolerance value. The default is 0.0001, and is generally suitable for most models. For significantly smaller models with gross dimensions on the order of 0.01 units, reduce the tolerance to 1e-6.
Description
Upon launching CAD geometry into Autodesk® CFD, a translation process occurs that converts from the native CAD kernel to an Autodesk standard geometry kernel. The tolerance used for this interpretation is the value defined by the AsmCoinTol flag. (Note that this tolerance is not used when transferring CAD geometry from PTC products.)
If geometric model in is incorrect after transfer into Autodesk® CFD, and shows one or more of the following issues, reduce the value of this flag to 0.00001 or even 0.000001:
