In RF module, we can right click a 3D plot or a slice plot, and "add plot data to export". A txt data is exported in this way.
Here is my question: I have a modified txt data, how to import and plot it in comsol?
Specifically, I have txt data which contained x y z coordinate and color data. I can import this txt data into a table in comsol. But when clicking "table surface" button, it said "does not contain filled data".
Please help me with this problem.
Thanks a lot

Hi
For plotting a data file, i hope the following procedure will be helpful for you.

1. Open Comsol, Right click on definition.
2. Select Interpolation.
3. Change the data source from table to file.
4.Browse the txt file you want to plot.
5. click on create plot.

Hi Janmejaya,

I just found this thread that discuss the problem which I also encountered. I have data file which is in 64x64 grid format and I need to display the data . I followed instructions you had given : Global definitions>functions>interpolation>data source>file>data format>grid
but at the end it come out with error message:
"interpolation arguments cannot have more than 3 arguments"

What had caused this error? Please help.

Regards
Fazlul
