Description of the bug

Hello,

When trying to load a .db or .cdb then I get an error saying:

DPFServerException: MeshProvider:39<-meshes_provider:40<-Operator(s) (mapdl::cdb::MeshProvider) does not exists in the registry !

I would like to get the named selections out of the .db file to show the model/mesh prior to solve.

If I solve a model then load the .rst or .rth for the model, there are no issues.

Steps To Reproduce

This is not a solved model solution but gives the example for meshed_region error

from ansys.mapdl.core import launch_mapdl
from ansys.dpf import core as dpf
import os

curdir = os.getcwd()
workdir = os.path.join(curdir, 'model')

mapdl = launch_mapdl(override=True, run_location=workdir, nproc=1, verbose=True, license_type="preppost")

### Create CDB Example

mapdl.prep7()
vnum0 = mapdl.block(0, 1, 0, 1, 0, 0.5)

mapdl.et(1, 187)
mapdl.esize(0.1)

mapdl.vmesh(vnum0)
mapdl.eplot()

mapdl.cdwrite('db', 'box', 'cdb')

### Read created CDB

curdir = os.getcwd()
filename = os.path.join(curdir, 'model','box.cdb' )

# ds = dpf.DataSources()
# ds.set_result_file_path(filename)
model = dpf.Model(filename)
meshed_region = model.metadata.meshed_region

Hi @giiyms,

Indeed DPF does not support .cdb files yet. This is in our To-Do list so I will classify this as an enhancement request if ok with you, or better yet I could close this one and start an Feature request issue (different template).

giiyms commented 1 year ago

@PProfizi sounds good. Is a way to read the .DB on the enhancement todo list aswell?

PProfizi commented 1 year ago

Hi @giiyms, Yes it is indeed. We plan on supporting both .cdb and .db but a timeline has not been set yet for those.
