Hello AzumaCs,

I've recently ran into the same problem. Mechanical uses to following code to print messages directly into the messages window:
ExtAPI.Application.Messages.Add(Ansys.Mechanical.Application.Message("Hello world"), MessageSeverityType.Info)

Hope this helps

Hello Thomas25,

Thanks quick response. I have read your comment, but I see something wrong.

I have information use the below python script in order to use ansys.dpf.core from Ansys local support Eng'g.

use script as below. . .

from ansys.dpf import core as dpf
path = "C:\Users\transient.rst"
model = dpf.Model(path)
print(model)

command print(dpf.Model(path) is run in outside Ansys and document is available below.
