Can't export surface mesh

Coreform Cubit
#1

Coreform Cubit Version: 2022.4
Platform: Linux

I have created a surface mesh on a volume, and I only want to export these surface elements to DYNA, and not have to create volume elements.

I get this error: ERROR: Invalid number of dimensions requested for mesh output: 0
ERROR: Could not export the data to a file.

I seem to recall this is possible with Cubit, maybe using sheet bodies?

Thanks

Hi Jeff,

Make sure you create a block with the surfaces that you want to export. Something like:

bri x 10
block 1 surface all
block 1 element type shell
mesh surface all
export lsdyna "shell.k" overwrite

This creates ELEMENT_SHELL cards

*ELEMENT_SHELL
       1       1       1       3       9       8
       2       1       3       2       5       9
       3       1       8       9       7       6
       4       1       9       5       4       7

Thanks,
Karl
