Incoherent Mesh

[davidgholmes]

I am trying to model a multi storey concrete frame but am having difficulties meshing the structure when I add the upper stories, with a error message coming up saying there is an incoherent mesh on the edges. I have looked through other similar posts and have used the settings as this post: http://forums.autodesk.com/t5/Autodesk-Robot-Structural/Various-problems-on-mesh-generation/m-p/3764..., but I'm still having a problem in one area.

It seems to be only one element in a core wall at a floor that seems to be the problem as shown in the attached screen shot.

Any suggestions to get the model to analyse?

Thanks

Freeze meshes \ panels and move node to get coherent mesh

PLease send us file to check it.

Thanks Rafal,

The problem seemed to solve itself somehow, but seems to have come back now!

Which mesh were you suggesting to freeze? The slabs or the walls? I also don't seem to be able to select any of the nodes on the meshed wall to move?!

The model is bigger than the limit to send through this, can I email it to you?

Thanks

MOdel is so inaccurate....Wall panels are not defined in wall (shaft) planes, claddings not defined in wall planes.

I suggest to remodel them but there is one quick way to correct meshes.

Mesh model, freeze meshes \ panels (all) then move nodes to obtain coherent mesh.
