fulcrum is on a distinguished road
Hello, I'm new to Ansys.

I need to model heat transfer in a pipe-in-pipe HE.

Inner tube has many thin extruded fins: 250 in total. Tube length 100 mm.

Now my question(s):

1) Is this problem solvable on a ordinary PC ? 6 GB of RAM, 2.3 GHz.

2) Any meshing methods advice before to start ?

Please see the attached pictures below.

Gert-Jan will become famous soon enough
My first guess would be that it is not possible on your computer. I would start with an axisymmetric case in 2D (fluent), if you can get away with this simplfication (ignoring 3D effects.
Try ICEM Hexa to create the mesh.
