import mesh to Workbench mesher
Is there a way to import any kind of mesh to Ansys Workbench mesher? I can not find that function...
Thanks for the answer in advance! |
Skin it.
Not yet...
At the moment, the ANSYS Meshing tool requires geometry to apply bocos, etc. so it can't take in a mesh without a geometry... HOWEVER... The Free (in Workbench) FE Modeler tool can import a mesh (such as a Nastran Mesh) and "Skin it", then you can send it from FE Modeler to ANSYS Meshing with the existing mesh or to remesh it, etc. Also, our Extended Meshing tools like ANSYS ICEM CFD or ANSYS TGrid can import 3rd party meshes (without geometry). |
Yes it can :)

Imported Mesh system...

Oh yes, But that doesn't get the mesh into ANSYS Meshing, it just gets it onto the schematic so you can import it into ANSYS Fluent or CFX by dragging and dropping those systems onto the Imported Mesh field.
This would be similar to just opening one of these programs (just use a Fluent or CFX system and launch them without a mesh) and then import the mesh directly into the solver. Attachment 6060 We are working on this and should be able to do a lot more with an imported mesh at some point... ;^) |

a bit of description and new question
Quote:
My whole problem arises from an axial fan cfd simulation, in which the rotor itself is surrounded by a fairly complicated geometry (not just a channel). So in this case Turbogrid mesher fails to build nice mesh for the complicated inlet/outlet domains, though It can make a suprisingly good quality mesh around the blades (especially with ATM optimized topology, the guy who invented that must be a genius). So the Turbogrid mesh is confined only to the rotor, but then I must connect the inlet/outlet meshes to it. But, as I'd like to simulate only 1 blade passage, it is advisable to minimize the numerical error arising from different interface areas (pitch ratio not equal to 1) between the inlet domain's outlet and the rotor inlet (as well as between the rotor outlet and the inlet of the outlet domain). I reached the point I wanted: so I'd like to start my inlet/outlet domain meshes from the rotor's mesh which is generated by Turbogrid (see my other post too: http://www.cfd-online.com/Forums/ans...tml#post290353). That is why I wanted to import the rotor mesh to Ansys mesher to build the inlet mesh using rotor's inlet/outlet. This solution looks a dead end (at least with current Ansys mesher), but I was able to export the mesh to Icem CFD and generate inlet geometry (by converting face mesh to geometry) and could do the inlet/outlet domain meshes there in Icemcfd and export those back to workbench to CFX-pre. My question is: can I do this latter method with Icem CFD without loosing the possibilty to exploit the nice parametric study capabilities of workbench (as Icem CFD is not a component system of workbench (why not actually?) ? Can I use some scripting feature of Icem CFD to update the inlet/outlet domain meshes, but keeping the simulation (mesh generation) automatic in workbench to make parametric case studies? Thanks for the answer in advance, again! And sorry for the long post... |
hmm...could be a good idea

Plugin error: Attach failed Unable to attach geometry Any other ways to send the geometry from FE Modeler other than in its own .fedb file? I used the templates as well: the stl template is not too good, as it would output all my cells just tris insted of quads, right? Is there a template for outputting to .iges from FE modeler? That would be nice... |
Skin...
You must skin it...
The skinning (Geometry synthesis) is critical for getting the model into ANSYS Meshing or ANSYS Mechanical. It is also required before you can convert the geometry into bsplines for output to IGES or Parasolid. |
confusion

Ahh ok. So does the "intitial geometry" feature only take into account the skinned geometry? So it disregards the components, right?
When I convert the initial geometry to parasolid will it respect the details of skin detect tool (e.g. tolerance angle) or will it respect the geometry sythesis parameters like vertex insertion angle? Thanks! What about the other method with Icem? Can Icem be connected somehow to a workbench project (eg via scripting) in Ansys 13? |
Can i import mesh from ICEM to ANSYS mechnaical with geomtery, as I have to implement boundary condition in ANSYS?

My .msh file is not getting imported in fluent.
Please help me out. |
what's the error message you are getting?
