MEshing problem with HELYX-OS
Hi Folks,
I am newbie in OpenFoam 4.1 and HELYX-OS 2.4. After a seriously difficult installation process, finally the software are working.
Now I am trying to create my first simulation by using a simple pipe with an inlet, and outlet and the pipe wall. The geometry is imported from .stl then bounding box and material point were defined, however the mesh was not created. I got the error message:
Code:
--> FOAM FATAL IO ERROR:
size 8776 is not equal to the given value of 40000
The log file:

Is any idea what can be the problem?
Thanks in advance, Feri |
