Vinc,

I am just starting with gidPro, trying to mesh turbine runners. What do you do to get your surface geometry into gridPro? I have tried the iges2gp and get errors. I have also tried converting patran and nastran surface meshes, but that just gives me a mesh, and I do not know how to fix surface topology to it.

Hi Bryan,

You should use stl files to import into GridPro.
But we should keep this topic for the converter. I will be pleased to reply to your GridPro related questions by email (vincent.rivola@rtech-engineering.com) or by PM as you want.

Regards,

Vincent

Hi there,

I am trying to use the options in gridpro2foam to create facesets for runtime data extraction.

However, for this to work I hoped that the face numbering would be identical when gridpro2foam is used with or without the --solid option. When having more than one 2-sided surface in gridpro it doesn't seem to work.

This is the face numbering when not using the --solid option

4
(
Volute
{
type Volute;
nFaces 8250;
startFace 315159;
}
Inflow
{
type Inflow;
nFaces 2880;
startFace 323409;
}
Pipe
{
type Pipe;
nFaces 2592;
startFace 326289;
}
Outflow
{
type Outflow;
nFaces 504;
startFace 328881;
}
)

and this is when using --solid 3
(BC 3 and 5 are 2-sided surfaces in gridpro)

6
(
Volute
{
type Volute;
nFaces 8250;
startFace 314655;
}
Inflow
{
type Inflow;
nFaces 2880;
startFace 322905;
}
Flange
{
type Flange;
nFaces 504;
startFace 325785;
}
Pipe
{
type Pipe;
nFaces 2592;
startFace 326289;
}
Outflow
{
type Outflow;
nFaces 504;
startFace 328881;
}
Flange-bis
{
type Flange-bis;
nFaces 504;
startFace 329385;
}

Can someone explain to me why the face numbering is not identical for at least the first two patches?

Furthermore, I get the following output:

...
Not processing BC -1
Processing BC 1
Processing BC 2
Processing BC 3
Processing BC 4
Processing BC 5
Processing BC 6
Processing BC 5003
...

The last BC seems a bit odd to me as the connectivity file only includes 6 BCs numbered from 1-6.

Per

Dear Stefan,

The last version of GridPro2Foam is 5.12.
I am going to upload it to our server and will put the link here in a moment.

Hi,

I have some trouble doing a proper conversion of a very simple periodic mesh. The problem is that one of the periodic boundaries is moved during the conversion.

Looking through the code it seems that the periodic angle is hardcoded - is this intentional? If I change the period in Gridpro to match the hardcoded angle the mesh looks fine but I rarely have a period matching this :-)

double periodicAngle = 360/11.;
double theta =  -(atan2(n1->z,n1->y)>atan2(n2->z,n2->y)?-periodicAngle*M_PI/180.:periodicAngle*M_PI/180.);

I am using gridpro2FOAM v5.12.
