Icem 12.1 - distance problem
 
Hello,

unfortunately I have a big problem with the distance between two points.

For example I create these two points (0.1 0 0) and (0.4 0 0). When I'm now measuring the distance between them Icem shows me "0.30000000447034".

When I'm importing a geometry Icem changes the distances too.

My mesh should be very accurate.

Can anybody help me? Thx...

PS: sry wrong forum :)

It's also the same problem when I rotate and copy parts of the geometry. The distances are always changed a little bit :(

It's a gap of 0.00000000447034, which is very small.
I don't think any mesher or CFD code can handle such an order of precision.

It means that 0.3 is equivalent to 0.30000000447034 for all softwares ;)
