Can you share your Ansys model (.cdb format)?

Hello Nils. Thank you for the quick response.

I've been trying to save the model in the suggested .cdb format but i can't figure out how to do it. I'm using the workbench environment, not the APDL, might that be a problem?

Anyways, i'm working with a very simple geometry to which i apply no boundary conditions and perform the free-free modal analysis for the first 12 vibration modes. The problem is straighforward and the solution is generated smoothly.

With this said, let me frame my problem. I'm trying to figure out how to export some quantities from the modal analysis, using ANSYS mechanical 2020 R2, as i will require them as an input to a flexible multibody code.

The quantities i need to extract are:

1. nodes coordinates;

2. nodes masses;

3. natural frequencies for each mode shape;

4. eigenvector for each mode shape.

The generated .dat and .out files contain the quantities 1. and 3. respectively. However, i cannot find the quantities 2. and 4. in any of the generated files. Do you know where i could find these quantities? Or if i could automate ANSYS mechanical to create a .txt file with the quantities i require?

I hope i'm not being to confusing. Thank you once again.

Hello Nils,

Thank you, it was helpfull. I've already saved the file in .cdb format and i'm attaching it to this message.

However, and as i said before, i'm using a simple geometry to understand how to extract the outputs i mentioned in the previous message. Do you have any tip on how i can do it?

Thank you once again.

Hello, this research is to execute a modal analysis of the functionally graded piezoelectric material rectangular plate and the results shown are from the ANSYS workbench. May be helpful for you.
