Fuse and meshing

Tried to find a solution in documentation.

I Create a model in Salome Meca 6: one box (30000x50000x30000),assumed size in mm. In this box I placed a Ø197mm pipe sticking in from one of the sides. So it is not a complex model i Think.

My aim is to simulate a blow out from a steampipe into free air, for this I created a model that shows steam from a pipe blowing into the box. This to create the boundry conditions.

I first created this with 2 meshes (cylinder and box), but this causes problems with exporting the model as a MED file.

I then thought about “fusing” the model to prevent this problem. I then received an error that I can’t perform this action.

My question(s), how do I prevent this message? Is there anyone the can help me with a tip on this matter, or is the difference of the models too large? Is the base model assumed to be in mm or is the dimension just a factor that indicates the size difference if I convert the model to meters the difference in size will be the same. Any tips on the way to model this and perhaps create the simulation.

Reply to myself. I found out on how to create the mesh i needed. By making a compound mesh.

Hi RJ

I am not a FEA guy, hence I don't understand from you description what geom model and mesh you need. As the geometry you use is simple it should be easy to create a proper model and mesh it, if one understands what is needed.
