I don't have a model in front of me, but as Mohammad stated, I do believe PowerGraphics plays a part in this.  Try a small test model with if off, and then on.

However, to your actual question...I don't believe PRNSOL is restricted to the surface nodes.  I believe it outputs results for all selected nodes, whether interior or exterior.  If you only wanted output for exterior nodes,  you would have to deselect all interior nodes.

Riccardo,

What are the PowerGraphics settings in your model?

Below is written in TFM:

PowerGraphics can affect your nodal solution listings. For PowerGraphics (
/GRAPHICS
https://www.mm.bme.hu/~gyebro/files/ans_help_v182/ans_cmd/Hlp_C_GRAPHICS.html,POWER),
results are listed for the model exterior surfaces only.

I hope this helps.

Best,
Mohammad

Dear Mr. Gharaibeh,
I tried both ways: /GRAP,POWE and /GRAP;FULL. Same outcome.
Thank you very much

Best regards

Here is what ChatGPT suggests:

=====

If ANSYS is showing results only for surface nodes when using PRNSOL, it
suggests there might be a selection filter applied, or the view might be
restricted to surface nodes. To ensure that PRNSOL outputs data for all
nodes, make sure no specific selection is limiting the nodes. Here are a
few steps to ensure you're getting the results for all nodes:

1. Clear Any Previous Selections: ANSYS ALLSEL,ALL ! Ensure all entities are selected

2. Print Nodal Solution Data for All Nodes: ANSYS PRNSOL,U ! Print nodal displacements (for example)

3. Check Element and Node Selection Status:

nodes are selected ```

4. **Reissue the PRNSOL Command:**

```ANSYS PRNSOL,U ! Reissue the command to print nodal displacements ```

If you've followed these steps and are still only seeing results for
surface nodes, it could be due to: -

**Viewing Limitations**: Sometimes, the graphical display might be limiting
visibility to surface nodes. Ensure you're checking the text output in the
ANSYS command log or output file.

**Model Definition**: Verify that your model actually includes internal
nodes. In some mesh configurations, internal nodes might not be present if,
for example, you're working with shell elements.

If you continue experiencing issues, providing a snippet of your ANSYS
script or a detailed description of your model setup could help identify
the problem more precisely.

Again, I hope this helps.

Best,
Mohammad

Dear Mr. Ridzon,
I carried out tests with both options of the /GRAP command. Only the exterior nodes' data were output.
Thank you very much

Dear Mr. Gharaibeh,
I selected everything and checked that everything was selected before issuing the PRNSOL command.
As for the Viewing limitation, I directed the output both to the APDL GUI pop-up window and to an external file: same result, that is, only the external nodes were listed.
As for the Model Definition".... well, it's reassuring for the human race that ChatGPT still has flaws.

Thank you very much
