Solver Failure - Static Compression Simulation

Simulation Resistance of materials
1

Hello

 

As part of a project in my studies, I am carrying out a compression simulation on a simple part: an extruded paving stone.

I apply a force of 100,000 N to the aluminum alloy part. I ticked the box for large displacements given the forces involved.

When I run the simulation, SW returns the error message: Solver failed.

 

What I observed:

- When I put only 50,000 N, the simulation runs (but I need at least 100,000 N)

- I checked the automatically selected solver option, but I still have the problem.

 

Do you know what this can be due to? Do you think SW is at its maximum capacity?

 

Thank you very much for your help,

Florent

Hello

Solidworks has no limit as such since everything is based on the strength of a material with no calculation limit on a normal machine.

It's difficult to answer without seeing the play because you say :

(a simulation of compression on a simple part: an extruded paving stone.)

It all depends on the form, because if you are talking about a great displacement, you should know what led you to this presupposition, whether it was real or wrong.

Can you post your piece and if it's an ASM make composition to go.

Yes indeed, here are the dimensions of the room as well as the SW file:

Width: 60mm, Length: 100mm, Height: 130mm, Thickness: 3mm

Thank you

Ben!! Uh

  1. You don't tell me where you exert force (if it's force)
  2.  You didn't attach your simulation study! So I can't help you more

You have to do

  1.   Save your file with the simulation study even if it is banana. This will show me the settings you used.
  2. make File ==> composition to take (or pack and Go if you have a version equal to or greater than 2017)
  3. In the choices you have to check the results of your simulation study so that they are attached.

Give me all your design intentions too: including why you are making this simu with the parts that go around it.

Here is Voili Voilou for now

Hello

  Having only SW 2013 I couldn't open the room, but here are some clues for your simulation:

    - Do the imposed trips really achieve a complete connection?

    - reduce the size of your mesh (since your model is a case)

    - model the part as a shell earlier than volume

I am carrying out this study in a first quasi-static approach to simulating the compression behavior of an automobile crash-box (profile at the front of vehicles allowing shock absorption).

This part is therefore recessed on one side and subjected to the force of the impact on the other side.

I attach the simulation file

Hello

As your real need is becoming somewhat clearer, I invite you to read my answer on the subject.

Even if the title is curious, it's the same crash test problem if you take the time to read the exchange.

In other words, since Solidworks simulation only works in the elastic field (and never in the plastic field) and does not simulate stamping or breakage, you will not achieve your goals in static.

If I have misunderstood, however, you should know that in any case you have to send the whole part file with the result of the simulation using the function I have indicated.

As it is! Your file is completely unusable.

Kind regards
