Dear All,

I am trying to convert some Plot3D meshes into the OpenFOAM format. What I am doing is to download some meshes from, for example,

http://turbmodels.larc.nasa.gov/backstep_grids.html

and to convert them using

plot3dToFoam name-of-the-mesh

But I get this error:

new cannot satisfy memory request.
This does not necessarily mean you have run out of virtual memory.
It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library

Could anyone help, please?

Thanks a lot,

Hi Samuele,

Did you solve the problem?

[samiam1000]

Dear Adoledin,

indeed, what I did was to generate a new mesh similar to the one available in the link I post in my first message.

Sorry!
