  1. I agree that the documents available either stay too abstract wrt the math behind it, or simplify matters too much. Can’t use these documents to convince clients or experienced analysts of the technology. The results are there, but we need to understand how it works. What would be very helpful is if you would work out a particular simple example in detail, for example the infamous plate with hole. For example show/explain analytically for this case which equations are being generated, how displacements and stresses are generated from this, and what one adaptive step does.
  2. From a critical client from the railway train sector, I got this question about the phenomenon “meshless analysis”. Every client who outsources strength calculations these days, knows that FEM is immovable related to “mesh”. So they are often quickly skeptical when they no longer see mesh and nodes in my calculations reports. Certainly clients who do also FEM calculations themselves. So this becomes more and more an issue over here. I’ve seen the many equations in your white papers. I know quite a bit about mechanics of materials with all the old classical formulas etc. etc. But this explanation with formulas on the white papers are much too complicated for me. Certainly an average customer will not be able to understand this at all. Nevertheless I have to explain the customer why this “meshless method” is as good as the classic mesh method. Now, the question is, can you make a short explanation in layman’s terms, or with help by figurative clarification? Without going into the depth, but showing the essence of the working of your method. I can imagine that other Simsolid users sometimes get this question too. So maybe such a simple explanation of the “meshless method” – if possible – would also be a good addition to your quick-manual.
  3. It would be nice to be able to define the gravity load along a self defined coordinate system
  4. Awesome!!This is really useful.just what I need in the current project.
  5. Is there a way to select by material, followed by “hide unselect” ?So I’ll be able to show results by specific material, instead of part-groups/sub-assembly’s.
  6. No rigid motions No disconnected parts No geometry defects So, everything is fine with the model But: with 3 adaptive solutions, it does not solve (saying: insufficient constraint) with 2 adaptive solutions, it does solve without problem Why is that?
  7. OK, I think that’s a good advice.I was already thinking too complicated about the solution.Thanks and I’ll let you know if the problem has been resolved successfully.
  8. for a customer we have to solve a fairly complex issue.And I wondered if I could solve this problem (evt. in part) with simsolid.For the details see the attachement
  9. I have a construction of which I have removed various components such as batteries, wiring, toolboxes, etc. etc. The total removed mass is 3500 kg and has known coordinates for its own center or gravity. Now for the analysis this mass without volume has to be added back to the model, to get the actual weight.In Nastran it is called a point mass. How can I do the same within Simsolid?
  10. Today i had remade all connections. First i had set the auto connections at a smaller gap size and higher resolution. Then i got the message again and again with check possible rigid motions, this time it shows the loose components (a lot components and very much bolt/nut/washer sets). It cost a lot of time to set all the contacts manually. I have also suppressed a lot of parts and fasteners because of time consuming (at setting manual contacts). After analysing again i got now results! Thank you for helping. I will send you the .ssp file for your info and development of Simsolid. I do a lot of this engineering jobs, also for the future. I hope you continue to develop for efficiency and better automatic contacts at large assemblies.
  11. Thank you for reply. Ok i will work through the options and try other connections. unfortunately that it is difficult to find where the problem exactly is.This is a confidential project. Where can I send the model for verification?
  12. Hello, We have a large assembly (structural steel frame) including a lot of steel beams and bolts/nuts. The assembly contains fully defined connections and constraints. After solving the analysis we got the message: “Unable to solve equation system (status 17, 4276, 0). The structure may not be sufficiently constrained. Do you want to check possible rigid motions?” After directly checking Rigid motions we get the message: “The structure is sufficiently constrained. No rigid body motions was found.” These are conflicting reports. Now i have to check manually every part and connection in the large assembly. Do you have some tips? Thanks.
  13. Great and fast answer! We will try this. Thank you again. Regards,
  14. Hello, Is it possible to update a model in Simsolid with an existing analysis? We have a large existing analysis with a lot of conditions (custom contacts, loads, etc.), and this must be updated with a model revision made in Onshape. We use Onshape professional and Simsolid Power (desktop). Thanks for the info.
  15. Thank you very much for your answer. I mean by posed resting on ground . I thought that immovable meant built in ! So I’ll try with that.
