Test request - 1D flow

[KgoaOT]

I have done the implementation of 1D flow using FLUID SECTION definition which works similarly to the BEAM SECTION and SHELL SECTION
An example on the CalculiX manual http://feacluster.com/CalculiX/ccx_2.10 ... ode13.html).

I have attached the example file here:

1DPipe.fcstd

(8.16 KiB) Downloaded 74 times

In the example file the is a pipe with an inlet and outlet. The inlet pressure and Inlet flow rate is used to determine the outlet pressure.

Currently the results from the analysis are not read into FreeCAD because 1D flow results are not supported. Furthermore visualization of the results is also another thing that needs consideration.

The branch can be found here: https://github.com/stoflap/FreeCAD/tree/FluidSection

Sounds interesting...

@KgoaOT:
wow cool, would you post an example analysis?

Damn small screen ... I'm on my smart phone ATM. Sorry ...

I did a rebase on master, some code formating and fixed z88. All can be found on branch:

https://github.com/berndhahnebach/FreeC ... fem1dfluid

Some result reading should be implemented before we gone merge it into master IMHO. @KgoaOT: Are you gone plan to do this?

Yes I will also look into this.

The results for 1D flow are now supported:

Taskpanelshowresult.PNG (65.23 KiB) Viewed 2217 times

as well as in vtk. But in vtk we can only currently view the results in terms of the nodes:

the link to the branch can be found here:

Feedback and comments will be much appreciated.

You only have been using a mesh with 7 nodes. If you would use 100 it would be better or am I wrong?

Can you post an updated example the earlier one is giving a number of errors
