Output results in rpt.file

ron.kunz over 7 years ago

Dear all,

In the past an outputfile has been created for the stress tensor.

This outputfile is an rpt.file

Added I have a picture of these results.

I would like to know how to create these kind of files.

I guess it should be somewhere in Results --> create --> report

In the releaseguide I also do not find it.

Thanks in advance.

You are looking in the right place

Results: Create / Report has 3 methods:

Preview: gets written to STDOUT

Overwrite File: creates a new file

Append File: appends data to an existing file

[You can control the file name on the "Display Attributes" tab]

You should use the "Target Entities" tab to select entities of interest.

Otherwise you will get a report for all entities in the current viewport.

Note:

STDOUT is the command window if you start Patran with the '-stdout' option.

This is not a default. That may be why you don't see anything.

Give one of the file methods a try.

Yes, Results: Create/Report is the tool to use. Pick you result case and result type as usual, and in the listbox at the bottom select the quantities you want to output:

Under the other icons you control which nodes/elements you want to use, the formatting of the report, and the result manipulation options to use.

You can find full info on this in the Patran help: look in Results Postprocessing/Reports:

I hope this helps!

Thanks Ken and Darrel,

"Overwrite file" is indeed the one I was looking for.

An additional question on this topic is: is it also possible to get the forces of bolts written in this rpt.file?

You should be able to write to the report any results quantity you can plot. So for example if you've modelled your bolts as beam elements, then you should have "Beam Forces" results, which you can output to the report.

Regarding the Bar forces which are written down in the .rpt-file.

I have a model (not mine) for which the beams are sometimes consisting of 2 elements and sometimes 4 elements. So if one wants to read the axial forces one has to read the x-forces. However it is not clear if I have to add all elementforce (2 or 4) or just read 1 force to have the exact value for the axial force? For example below gives me the forces for 4 cbars which is one bolt.

Is now the axial force 848N or 4x848=3392N?

377408 848 557 826

377409 848 557 826

377410 848 557 826

377411 848 557 826

Thanks.

With: Tools - Results - Bar/Spring Force moments I can plot the same results.

So if I want to plot the x-component I have to select an element. In this case I select 1 element and the force is 848N. So if I select al 4 elements it shows me 4 times the value 848. Same as the rpt file of course. But is now the axial force of the bar 848N or 4 times 848N? Thanks

Ron, think back to your statics course. Each bar load is like force in a freebody diagram. (it helps to draw a picture).

Are the elements connected end-to-end? In other words, the 2 or 4 elements form a line (connecting node 1-2, 2-3, 3-4, 4-5)? If so, the axial force will be the same in each element (assuming no intermediate axial loads are applied).

However, if they are connected in parallel (2 elements from node 1-2), then you have to add the forces together.

Dear all,

For collecting data I would like to change a setting:

In the report file I would like to switch from Element Tensor to Nodes Tensor.

Where can I change this setting?

Thanks in advance.

Target Entities icon on the results application window, change the display control to Nodes.

best regards
