Open frame3DD result file (*.OUT)

[johnwang]

Hi,

I have written a frame3DD result file (*.OUT) importer followed this: https://github.com/FreeCAD/FreeCAD/blob ... Results.py

Since OUT file extension is not supported by fc at the moment, when you try to open it, fc will show a message saying not supported.

To try this new open:
1. Rename the original importCcxFrdResults.py to other name, which is located at Freecad\Mod\Fem\feminout to save it
2. Copy my one into this folder
3. Rename frame3DD's OUT file to FRD file, that is exA.OUT-->exA.Frd
4. Use fc to open that exA.Frd

If fc support OUT later, my one could be named importFrame3DDResults.py

Regards,

John

would you post an example out file?

would you post an example out file?

You could get the examples from frame3dd site here:

name your module "importFrame3DDResults" and place it in "feminout"

place following line in init.py in Fem above this line:

https://github.com/FreeCAD/FreeCAD/blob ... nit.py#L51

Code: Select all

FreeCAD.addImportType("FEM result Frame3DD (*.out)", "feminout.importFrame3DDResults")

Start FreeCAD --> open an out file --> enjoy


exA.out from the link you provided ...

if you use github, you could make a PR and we will include it in the main repo

on example exH.out I get this error:

Code: Select all

ahh forgot to write cool stuff

[bernd]

in your module is still a lot commented calculix specific (eigenvslue, flow, etc) code. Have a look here on Z88 result importer what is really needed and what not. https://github.com/FreeCAD/FreeCAD/blob ... Results.py

on example exH.out I get this error:

Frame3DD sometimes doesn't write displacement for all nodes. Have to deal with this.

Double click the result node, one can drag to view the result animation. So cool.

One thing I noticed, fc fem result obj only defined one load case. For displacement is like this:

Code: Select all

mode_results["disp"] = mode_disp

I tried in a loop:

Code: Select all

mode_results["disp"+str(LCnum)] = mode_disp

I got an error message from the compact mesh tool.

For frame3DD, most time needs load case more than one. Hope fc fea could support multi load case.

simplest workround, create one resultobject for each loadcase. Like in a frequecy analysis we create one result object for each mode shape. But you can use the same result mesh object for all result objects.
