Hi all.
Colleagues, please tell me.
I did the calculation in LS-Dyna Prepost and I received a d3plot file.
Can I test it for fatigue in ncode in Workbench?

[danielshaw]

Yes, Ansys nCode Design can read LS-Dyna results.

Thanks for your reply sir. How to properly load a d3plot file into ncode workbench?

[danielshaw]

If you are using Mechanical 23R2 or later, I recommend using the Ansys nCode DesignLife embbedded Add-On.

If you cannot use the Add-On, the FE_Input glyph can read a .d3plot file.

Thanks for your reply sir.
My question is how to import the d3plot file, which was generated when solving in LS-Dyna (LS-Prepost) into the Workbench ncode.
I tried the method through the External Data module, but it didn’t work.

How to do it?

It appears that you are attempting to use one of the Workbench integrated Ansys nCode DesignLife systems as a standalone system, which is not supported. The WB integrated systems must be linked to solved Mechanical systems.  If you want to access a standalone DesignLife system, you must use the DesignLife system in the Component Systems section of the WB toolbox.

That system provides access the the standalone Glyphworks interface.  You can use that interface to build a flow and access the .d3plot file using the FE_Input glyph.

Teaching how to use the glyphworks UI is beyond the scope of this forum, but there is a DesignLife training course available on the learning hub, and worked examples available in the DesignLife Help.

Thank you sir everything is clear.
There are several questions about the interface. May I ask them? I calculated a drill with attachments, the drill drills into rock (10 mm die). Nozzles are the object under study.

1. How to set your own/required material and SN curve for the test attachments on the drill? Should they be separated somehow?

2. What if there are several objects under study and their materials are different. How to assign material to them (each)?
3. How to set the load for calculation? In fact, not a load, but only to understand the fatigue of the objects under study, according to the calculations performed (d3plot)? Is there a choice of timesteps, for example, select the last step and look at fatigue on it? But I don't see fatigue:

4. For example, the drill drilled a 10 mm die in the LS-Dyna calculation and recorded it in d3plot. We chose the extreme step and looked at fatigue. How can we now scale this fatigue to a larger drilling volume? For example, at 1000 mm?
5. If temperature was also studied in the calculation, what needs to be specified so that it is taken into account when calculating fatigue in the encode? Temperature data in the material? What else?
6. Also, can temperature calculations be scaled to 1000 mm of drilling, i.e. calculate how hot the object under study would be after 1000 mm? This gives an understanding of whether the solder of the bits will withstand the body of the drill.
