Is there a way to taking moment reaction from fixed support locations of b32r element? I can easily read reaction forces of fixed support locations from .dat file but I cannot find a way to take similar output format for moment reactions.
Thank you for your concern. I did not understand clearly that changing to cylindirical cordinates. Actually my main problem is, I cannot write outputs of moment reactions like writing reaction forces output of fixed support location.
As far as I know I can use *SECTION print command with only surface option. In my case, I have two beam(b32r) model like in the figure below. I appy a concentrated load on the intersection point of two beams and apply fix support on two ends.
Thank you for your answer. I tried the *EL FILE,Output=3d, Output=2D, SECTION FORCES but, the moment reaction results differs with the ansys or other fea softwares even if reaction forces of fixed supports are both same with calculix and other fea softwares. I have taken the moment results from vtkpost and compare with the terminology which i shown you below.
Again it has not to be major changes in values? Because the reaction forces are calculated truly. The solution that you suggest will not work( even if i said that i tried and nothing changes). So it has to be different solution of the problem.
CCX structural elements aren’t true structural elements but are created from brick elements, so there are only 3 translation degrees of freedom, no rotations. Some additional calculations are needed in order those elements being representative of a beam section (available for a limited number of cross sections). The output has to be requested with the key: *SECTION PRINT
Check the manual about this key: ccx_2.19.pdf (dhondt.de)
It works and I can see some output printed on my *.dat file:
statistics for surface set S1 and time 0.1000000E+01
total surface force (fx,fy,fz) and moment about the origin(mx,my,mz)
-8.203642E-09 -7.319032E-09 -9.999600E+02 4.746009E-09 9.999931E+02 7.276014E-09

The point is that I cannot get both simultaneously available in the GUI.
S [STRESS (real), STRESSI (imaginary)]: true (Cauchy) stress in structures. For beam elements this tensor is replaced by the section forces if SECTION FORCES is selected.
is replaced: I can only see one or the other with *EL FILE. Ideally, I would like to have both available in the GUI.
Thank you for your answer. I could not understand clearly how can you get the force and moment values on the same screen with .dat file.
Could you please share what cards did you use to get this results? I can only see reaction forces in .dat file.
I am sharing my output commands below.
The stresses at the integration points are obtained by a *EL PRINT card,
the stresses at the nodes by the OUTPUT=3D option (default) on the *EL FILE
card, whereas for the section forces the SECTION FORCES option on the same
card is used (this option is mutually exclusive with the OUTPUT=3D option).
The displacements are best obtained in the non-expanded view, i.e. using the
OUTPUT=2D option. This means that for the present results the example had to be run twice: once with the OUTPUT=3D option and once with the
SECTION FORCES option.
from Manual: 5.14 Cantilever beam using beam elements
The problem is I have a beam model with b32 element, so there is no chance to define *SECTION PRINT, SURFACE… because the fixed support point is just a node not a surface.
I looked at the manual and cannot find *NODE PRINT card has a Moment reaction output option.Is there a way to write reaction moment of a fixed supported node or element with *SECTION FORCES or other options?
or alternative way
As I understand from the manual section forces of beams are written in local 1 and 2 cordinate system of the beam. Could we transfer these results to global cordinates and then see the results?
I guess in vtk post the SXY, SZX and SYZ are the moment reactions of node 1 but this values are calculated for local beam cordinate system. How can we turn these results to global cordinates?
