Elmer Discussion Forum

Hi there,
I compiled the latest version (revision 4259) from svn at Ubuntu 9.10. I import a .stp geometry to ElmerGUI for auto meshing but the result looks ugly, the mesh fineness is low. I tried to change Max.H and Fineness at the nglib item from Mesh --> Configure.. and remesh, but nothing happened.
I have another older svn revision (don't have the ver. number, just the date, 2009-5-17) at Ubuntu 8.04 and it seems OK for the same .stp. (the mesh is fine enough after the geometry imported).
Btw, elmerparam is not installed in my Ubuntu9.10 because I got a compilation error which not resolved yet. Could this be the cause?

Thanks and best regards,
wing

There was a small change... Could you please try the following:

- In the main window, choose View -> Cad model...
- In the cad model window, choose Model -> Preferences...
- Check "Restrict mesh size on surfaces by STL density"
- In the main window, open your stp file

Hi mal,

Thanks for your response. It works for me.

Hi,
I'm following the " Tutorial 1 Heat equation – Temperature field of a solid object " and after open "pump_carter_sup.stp" and getting the mesh I have a problem when I try to modify the mesh by altering the settings as it is explained " View -> Cad model...; Model -> Preferences... ":
When I click on "View -> Cad model... " a window called Elmer GUI geometry viewer is opened. I try all kinds of clicking and nothing happens in that window.
I don't know if something is wrong with my installation or if I should look for that option in other place.
Thanks for reading

It works in my installation.

There is a Linux Mint based virtual machine (VM) available at
http://www.nic.funet.fi/pub/sci/physics ... alMachines

The VM is huge in size but provides a certified user experience. This is often used at courses to give not only a fresh Elmer version, but also a complete installation of related tools.

There is also a CAELINUX.iso that can be on a virtual machine or livecd that includes Elmer. You could use either to see if it works in another environment.
