  Hello! I am interested in studying SPR3 element. This element works fine with shells (shell - spr3 - shell). According to LS-Dyna R13 manual beams also could be connected with SPR3 (elform1 - spr3 - elform1). But trying to use spr3 with beams results in memmory error:
  
  expanding memory to 94283 d 3849095 constrained spr 1
  expanding memory to************ d 3849095 constrained spr 2
  
  *** Error 70021 (OTH+21)
  Memory is set 4429334070282377342 words short
  memory size 325000000
  Increase the memory size by one of the following
  where #### is the number of words requested:
  1) On the command line set - memory=####
  2) In the input file define memory with *KEYWORD
  i.e., *KEYWORD #### or *KEYWORD memory=####
  
  Any ideas how can I solve the problem?

  Hello Estojia,
  Have you tried increasing the memory? How many beams and *CONSTRAINED_INTERPOLATION_SPOTWELDS do you have in your model?
  Have you tried with R14? You can download any version of LS-DYNA here:

    There is only one spr3 element and 2 beams.

  Hello Estojia,
  Ok, this is strange. Can you copy and paste the text of the input.k file in this thread? Then, I will have a look.
  Have you tried with a R14?
  Which exact version of LS-DYNA are you running? Could you paste the LS-DYNA banner from the d3hsp file as below?
  
  Reno.

  I am using free student verison of Ls-Dyna. I didnt try R14. Could student version be the issue causing this error? This runs ok with solids and shells. But with beams I always got memmory error.

  Hello Estojia,
  The student version is usin the R13.1.1 solver which is the same solver as the commercial version. There might be a problem with R13.1.1.
  Were you able to try R14? Or the new R14.1?
  Let me know how it goes.

    Same issue in other solvers

  Hello Estojia,
  I had a closer look at this and I think there might have a mistake in the R13 user manual. I ran a model with 2 beams connected with *CONSTRAINED_INTERPOLATION_SPOTWELD with the latest DEV SMP double precision solver and I get the following error message:
  
  Also, If I look at the DEV user manual, I can see the following:
  Also, the PID1 and PID2 expect a "sheet" which is represented by shell elements.
  So, I am not sure beams can be connected with *CONSTRAINED_INTERPOLATION_SPOTWELD. Let me double check with the developer.

    Hello Reno,
    
    Do you have any new info from devs about this problem?

  Hello Estojia,
  The developer said: "the SPR3 should be able to connect shells, solids, and beams.". He also sent me an example model with beams and I noticed that the gap between the 2 beams was 0.5 and the spot weld radius R was set to 5. In your model, the gap between the 2 beams is 4 and the spot weld radius R was set to 2. So, I set R=5 and now the model runs. I also tested with R=2.1 and it still runs. So, 2xR must be greater than the gap between the 2 beams.
  Give it a try and let me know if it works for you.
  
  Reno.

    Hello Reno, thx for your reply. I put distance between beams = 0.5 and put R=5. Still got this memmory error

    I think the main problem is in initiaiting :constrained spr 2". I am not sure what exctly it is
    
    expanding memory to 4732 d 1625159 constrained spr 1

    I accidentally found what causes the issue. SPR3 works fine with beams with MPP solver. But using SMP version results in memory error. Now, using MPP solver the simulation runs with beams+spr3.
    Thx for you help in solving my problem!

  I ran with R14 SMP double precision and it worked. Which version of LS-DYNA did you use?
