  1. Good morning, I'm running a transient analysis of 2 gears (one of them with a preload and the other one with an imposed rotation). When I run it with Optistruct I get 2 problems: *** ERROR # 4965 *** Maximum number of time increment cutbacks reached, analysis aborted. The biggest problem comes here, if I analysis the results, the contact status is 0 everytime. The gears rotate but they don't seem to have a good contact. Moreover, I get high normal contact forces at points where there should be any contact (see image attached). I also attach the .fem to make it quicker and the .out from the previous simulation Thanks!! 1107rem.out 1207manana.fem

  3. When I tried to run one of the tutorials associated with the Modelica set that comes with Activate , I received an error message shown in the attached screenshot file. That message indicates "Modelica compiler requires Visual C++ compiler version >= 10". If I download and install the "Microsoft Visual C++ 2015 Redistributable Update 3 RC", do you expect that will resolve this error?
  4. Following the y-bracket tutorial leaves the optimisation hanging on 100% and analysis fails, saying contact support. The optimisation is definitely no longer doing anything because the process has no load on CPU. Please see attachments. Any help on this would be much appreciated. Best, Darren
  5. Hello all, I am attempting to use some RBE3 elements to apply loads and I am receiving this error: A fatal error has been detected during input processing: *** ERROR # 774 *** When a grid's component has no stiffness, then that component cannot be an independent d.o.f. in an RBE3. RBE3 id = 270584 grid id = 326669 weighted components = 123 max d.o.f with stiff = 1 Would greatly appreciate some advice regarding this. Thanks
  6. Hello, I'm trying to load an .hm file created with a Student Version of the HyperWorks 13.0 (using Optistruct) into a comercial version of HyperMesh, but the following message appears: "The file specified is not a hypermesh database". What should I do? Thank you.
  7.

Because in my model the contacts seem ok (those are default contacts obtained after using boolean substractions of non-design spaces on a design space volume to avoid intersecting parts) Thank you in advance,
  8. Hello and thank you for your help in advance. The problem is that I'm trying to do an optimization, it runs during a moment but fails and shows to me the next message. Thank you again.
  9. HI, DURING A NON LINEAR QUASI STATIC ANALYSIS OPTISTRUCT GIVE ME AN ERROR: ERROR 1459 NLPARM IS REQUIRED FOR THIS SUBCASE TYPE HELP ME PLEASE
  10. Hello, I have not been able to sucessfully finish my analysis because of a fatal error. .OUT file says the following error "1 error have been detected in element processing procedure in processes with id = 5. Plese check the corresponding out file for details." What is a process ID? I have encounter this error before with differtent id numbers, but have not figured out what it means. My model contains Hinge joints and is a NonLinear quasi-static analysis. Thank you for your help.
  11. Can someone help me with the following error? *** INTERNAL PROGRAMMING ERROR *** in file "datasetFtoC.c", at location # 345. C1C2C.out
  12. I'm trying to run an analysis in Radioss and I get an "Error ID 54". Together with some more errors and warning. I attach the .out file (complete) ERROR ID : 54 ** ERROR IN INPUT FORMAT DESCRIPTION : IN BLOCK : 581 588 589 590 591 592 593 594 595 596 Thanks for helping new_0000.out
  13. Hello, I attached the .FEM file of the optimization I want tot run. I don't know what's going wrong, anyone can help me out? Meshed+Laminated.fem
  14. Hi Everyone, I am working with Radioss. I use TYPE 7 and TYPE 2 contact for this model (You can see from an image below). I set the Engine file as shown in image below. In the beginning, Radioss run normally. But later found a problem, Time Step Less or Equal Zero Error. (Previous model, I set nodal time step in engine file less than zero but Radioss run normally.) Can anyone take a look into my model what's wrong. what change, I have to make. Thank you in advance.
  15. I've installe HyperWorks 2017 Student Edition and added the environment variable "ALTAIR_LICENSE_PATH" , when i try to open hypermesh i get a license error ( as you can see in the attached picture). I've checked the ethernet ID and it matches the one I used to register my license. altair_lic.dat
  16. Hi, I am a student of Youngnam University in Korea.This time, I was going to get a student license and use it.However, an error occurred. I want to know the solution.I don't know if it's a license or my condition is wrong. Perhaps it is not a licensing issue.There's a file I analyzed last year. There was no problem last year. The file went on as it was. However, now the same error occurs as the attached picture. I don't know what the problem is. I need help.
  17. Dear Community, I am running a free-size optimization with a quite complex model and the run is aborted after a number of iteration for the ERROR 703. I receive the following message: Error in input data - Lower bound larger than upper bound44879 0.100408E+01 0.100000E+01 Error in input data - Lower bound larger than upper bound44882 0.100408E+01 0.100000E+01 Error in input data - Lower bound larger than upper bound44897 0.100408E+01 0.100000E+01 Error in input data - Lower bound larger than upper bound44900 0.100408E+01 0.100000E+01 Error in input data - Lower bound larger than upper bound44918 0.100408E+01 0.100000E+01 *** ERROR # 703 *** number of design variables = 47541 number of constraints = 37 error code from optimizer = 900 The optimizer failed to find a solution of the optimization problem at the current iteration. This error occurs in module "appdrv". Other information: If I change design parameters, the iteration where I have the error also change. If I remove ply drop-off constraint, the error disappears. If I reduce the design domain, the error disappears. (unfortunately, I cannot share the model) Any idea on how to solve this issue? Thank you in advance, Alessandro
  18. Hi, When solving my model in Flux 12.3, simple electrical steel strip in a coil, I get at error at the end of solving saying 'Failed Execution'. Under the advanced tab it says the following twice. 'CVCM3M - Sentence too long'. Does anyone know what that means? The model seems to solve correctly I have the flux density and voltage in my coils I would expect but why does flux then say there is an error? Any help with the confusing issue is much appreciated! Thanks, Ben
  19. Hi, I made a CFD simulation in Hypermesh using AcuSolve. After running the simulation and trying to display the results according to the video posted at the end, I'm required to select a file. However, no .log files are created as on the video and any of the ones created work. Also, unlike on the tutorial, I'm asked to select a Reader, and I don't know which one to use. Can anybody tell me how to make sure .log files (and any others necessary to display results) are created when running the simulation and which Reader to use?
  20. Hello, I am receiving a error when exporting an Abaqus file. "A segmentation error occurred. Do you want to save your model?" Any suggestions would be appreciated.
  21. Hi, I am trying to export Y-parameters of an array which includes 16 elements, hence, 16 ports. I want to create a .y16p file but every time I try to export POSTFEKO crashes and is not responding. I know it is a lot of data to export, but is there any other way to get Zparameter data? Thanks in advance!
  22. Hello, I'm having trouble with a CFD simulation. After running it in AcuConsole, the error "Error while executing acuPrep" appears. In Acusolve, this error disappears after specifying the eddy viscosity value, however, I don't know where or how to do that in AcuConsole.

    ERROR

    THE error is increasing what to do ? NC= 9000 T= 8.4895E-01 DT= 9.4325E-05 ERR= -5.6% DM/M= 0.0000E+00
  24. Hi, I've been trying to run a CFD simulation using the Hypermesh solver, however, I always get the same error (ERROR: error occurred executing acuPrep) and I don´t know what it means. Can anyone tell me why this happens and how to fix it? Thanks.
  25. I have come across "Segmentation Error" in my script. Script is for seleting particular surface elements and remeshing it with Spline option, and deleting prev. elements on user satisfaction. The script seems to be fine in context of Syntax and API uses. It would be helpful, if someone could tell me the common causes for this error. And, better, if someone could suggest solution to this problem. We thought it as error caused due to memory limitation. So, we have also used *clearmark every now and then. But, seems to not affect that much. Thanks, SAGAR MOTWANI
