MESH GENERATION ABNORMALLY TERMINATED! Please contact support services

have you used the "check geometry" command?  It's been a while since I've gotten one, but if I recall correctly it was either that it ran out of memory because of the extreme # of cells, or there was something wrong with the geometry itself.

wernyu, first things first, when does the message come up? during meshing? during solving? are there any errors in the solver window? have any iterations been completed?

i think chris is on the right track regarding geometry. if you've imported from inventor, make sure that the geometry is solid. meaning that it survives a CTRL-Q and it survives import diagnostics. if it can't, flow simulation is going to have a hard time.

the next thing is the assembly. eliminate interferences, eliminate invalid contacts. make sure that the assy is water tight (assuming an internal analysis here, if you're running external this is less important but depends on your options for how cavities are handled).

if you still have issues, double check it isn't a software problem. build a tube, pressure on one end, velocity on the other. does it run without issue? if so the software is working. if not, you've got bigger problems.

if the software is working and the geometry is good, you've got some kind of BC problem. start small. one or 2 components. basic BCs like a pressure and velocity, use air or water in the library, use standard pressure and temperature. it should run. everything should run like this. then start adding things until the problem happens.

for example last week i was getting the same error. it happened when i added a porous medium. when i looked at the definition, i had forgotten the point 0,0. added that point and the error went away.

Jared Conway,

     Thanks for helping, I'm glad that you can predict the problem much precisely.  i am using Propcad (a software that generating Propeller Geometries), to convert into Solidworks for my flow simulation works.  I have found that if i keep changing the curve of propeller shape at the corner, such as make fillet in some radius, say 0.1mm or 0.2mm which was allowabled in solidworks then the flow simulation can calculate it, Sometimes it works but some sizes aren't.  Well, i have confirmed the body is solid (without surface condition left). Also, i use "KNIT" to keep it tight after using some lofting.  but still need to refine the edge of solid body(which i do not know where was the problem occur), until the mesh generation can calculate the domain.  Quite wasting the time.  any idea or way to solve?

Thanks and Best Regards,

wernyu

Try upgrading either to SolidWorks 2013 or SolidWorks 2012 SP5.0. There were some mesh generation bugs in SolidWorks Flow fixed in those releases. See if that helps.

I get the exact same error when I try to flow simulate an APC propeller. When I simulate a simple static airfoil, it genrates no error. But when I flow simulate my propeller it gives up. I have also done the CTRL+Q import check but everything seems to be fine. It seems that although the geomtery is simple to look it is actually too cumbersome to flow simulate.

If anyone can take a look at it and confirm whether its the same problem or is it something silly i've been doing ...

here are the files for the propeller with study parameters set
