Is it possible to export beam deformations?

[CoenV]

Hello,

For some time I have been trying to export my beam deformations to Excel.
I think that the only way to do this, is by exporting the nodal displacements.
The disadvantage of this is, that the nodes are not sorted per beam.

If I then want to check a group for deformation in Excel, I must first link a group to its nodes, and then use these nodes to derive the maximum or minimum deformation. This process makes my Excel file too slow.

Is there a way to add beam numbers to deformations? Where the beam numbers are sorted? This will make my project a lot easier. Thanks in advance.

Edit: By nodes are not sorted I meant that that the nodes of a specific beam are not 1, 2, 3, …, 10 for example, but may be 1, 2, 4, 8, 12, …, 15. This slows the process in Excel a lot.

Cross reference the nodal displacements and the first node (or second) per beam:
E.g.:

Thank you very much

@sfr,

Whenever I do this, only the first loadcase is there in my table. Is it supposed to be like this?

[sfr]

You have to select the LCs you want. First one is preselected.

[CoenV]

Yes, that is exactly what I did. SOFiSTiK then still only outputs the first loadcase:

You have to select the LCs and press “OK”

Sfr,

That is what I did.
However, i wonder why you could select loadcases when ‘table’ was selected.
In my program that is grayed out.

Whenever I select the ‘Nodal displacements’, I can select my loadcases and I selected the ones I need and pressed “OK”.

So it might be a problem that I am unable to select the loadcases under 'Table"?

[sfr]

Then I honestly don’t know why it’s not working

I have written all the steps for your help related to Export Beam Deformations -

Linear Static Analysis

To export a deformed body, right-click on the results folder in the Simulation study tree and select “Create Body from Deformed Shape…”

You can specify the option to create the body as a new configuration or save it as a new part document in the location of the active document.

The deformed body is saved as an imported solid body with no feature history or external references. If the analysis is rerun with a different boundary condition setup or with updated model geometry, the deformed body will not update. A new deformed body will have to be exported to reflect the updated results. If the new configuration option is used, a new configuration is created with the original part model features suppressed and a new imported feature is inserted at the end of the feature manager design tree.

For an assembly analysis, the resulting deformed body is saved as a multi-body part. If the configuration option is selected, a multi-body part is saved and added to a new assembly configuration. Both the part and configuration share the same specified name. The original assembly components are suppressed in the new configuration.

Nonlinear Static Analysis

The deformed body is exported using the same process. Basically, I am using this software to design the best ERP partner in Kolkata The difference is that a plot step can be specified for the export. If a loading condition is specified using a user defined time curve, then the deformed body could be saved out at specified load increments. For instance, the deformed shape could be exported after half the load is applied.

Troubleshooting

Error Creating Deformed Body

Two potential issues may arise during the creation of a deformed body. The first issue is when an error message appears after selecting the green checkmark to create the deformed body.

Error: Unable to sew faces together. Creation of deformed body failed.

The error message usually appears due to an ill-defined mesh. The mesh is too coarse to capture the geometry correctly in the deformed state. The resolution to the issue is to rerun the analysis with a more refined mesh and retry saving the deformed body.

To complicate things, the error message may pop up when working with a good mesh, but is created using the “Standard mesh” option. The failure seems to occur when the deformation levels go beyond small displacements. Along with these processes, you can also migrate the best expense software in Kolkata related to this. The “Curvature based mesh” option has been very consistent with saving a deformed body. When the process fails due to a poorly resolved mesh, adjusting the auto mesher settings and/or applying additional mesh controls to refine the mesh usually resolves the problem.

Resulting Deformed Body Does Not Match Result Output

The second potential issue that may arise during the creation of a deformed body is the resolution of the deformed body saved from the analysis results. When the deformed body is opened in SOLIDWORKS, some surfaces may be missing or highly distorted. The process the software uses to create the deformed body is listed below.

When the deformed shape of the model is exported, the software creates a cloud of points with a standard number of locations coming from deformed node locations to represent each surface in the model. From the cloud of points, the deformed surface geometry is then created.

For complex surfaces, the number of points is too small to correctly represent the shape of the surface. A workaround is to split the complex surfaces into a subset of smaller simpler surfaces and rerun the analysis. The resulting deformed body should then have a better surface resolution.

The images below depict the original and deformed bodies of a hand wheel. The filleted surfaces where the spokes meet up with the rim were highly distorted in the deformed body. Solving the analysis with a more refined mesh along the surfaces did not resolve the export issue.

The deformed body export problem was resolved by using the SOLIDWORKS split line feature to break up each surface into four separate simpler surfaces. The images below depict the updated hand wheel’s original and deformed bodies.

Best Practices for Exporting a Deformed Body in SOLIDWORKS Simulation

• Use the SOLIDWORKS split line feature to break up complex surfaces into smaller simpler surfaces
• Use the curvature based mesh option
• Add mesh controls to resolve the mesh in areas where high strains are expected

Hope this will helps you properly.
