  4. Hello Sir,

    I am doing a rollover analysis of a bus, for that i have given initial velocity as 10mm/s in the SET, but its just deforming at the place where the velocity is given

    Can u just help me out on what I should do to make the bus rollover on the platform.

     

    Thankyou

  9. Hi Karthic, You can create an output block (Analysis>>Output block>>select node from the the option) for the node, and provide the required output request, that is REACX, REACY or REACZ which are the X, Y and Z X reaction force on the node. Please go through /TH/NODE in the Help Menu which explains about the various output variables available for the time history for nodes. You can also go through this webinar which shows creating output blocks in RADIOSS: https://www.youtube.com/watch?v=Ef7Spn-j7fA&index=6&list=PL1u26y75SCrA_BOCLaSewVCNY7xRvCTnA
  10. Hi, I am doing a snapfit problem in RADIOSS. I want to get the reaction force at fixed master node of RB element. How can i ? please help me
  11. We are trying to integrate sine wave (sine wave 50Hz from function generator (hardware)) in VisSim using Trapezoidal block, we can see the integrated output in oscilloscope of VisSim but the SPWM of the same cannot be seen on DSO(hardware). We are using GPIOs of LAUNCHXL-F28027. We get the SPWM for first few seconds and later it shows a constant output of 3.3V. We are comparing Cosine with Triangular wave of 1000Hz. What can we do to see the SPWM on DSO?

  13. Hello Prakash,

    I am trying to simulate a torsional rigidity test on a FSAE race car chassis and I need help assigning proper beam end releases at the suspension nodes.

    I am trying to simulate a ball joint with this configuration - 

    pin a  = 456 and pin b = 0. I this correct as I am unable to get the desired motion in the setup.

    The hw help says pin a and b should be values which are not intended to transmit forces. Should the pin a be  = 123 instead?

     

    Thank you

  14. I am trying to perform a 1D beam element analysis on a formula student race car. I need help regarding the application of beam end releases at the suspension nodes. Can someone confirm this setup - Node 1 ie. pin a = 456, node 2 ie pin b =0 - for simulating the a arm with a ball joint is correct or not? With this, I am unable to get the rocker(bell crank to rotate). Thank you

  16. @Ahanvoth The attached model is simple plate (5mm) with pressure applied. I have included gauge optimization in the model which varies thickness from 5mm to 0.1mm. The attached h3d files have thickness variations and displacement results. You can study the results for corresponding change in thickness.
  17. What do I do with these file types?
  18. Hi again, it's been a while since I used Abaqus and I am facing the same issue. Abaqus tells me: The model "test" has been created. The part "PART-1" has been imported from the input file. WARNING: Unknown assembly level element set RIGIDS. This occurred while processing rigid body definition. The rigid body definition will be ignored. WARNING: The following keywords/parameters are not yet supported by the input file reader: --------------------------------------------------------------------------------- *KINEMATICCOUPLING The model "test" has been imported from an input file. Please scroll up to check for error and warning messages. When trying to run a job, the following pops up: The job "Job-1" has been created. The job input file "Job-1.inp" has been submitted for analysis. Error in job Job-1: NODE SET ASSEMBLY_LOADSET HAS NOT BEEN DEFINED Error in job Job-1: A CONCENTRATED LOAD HAS BEEN SPECIFIED ON NODE SET ASSEMBLY_LOADSET. THIS NODE SET IS NOT ACTIVE IN THE MODEL Job Job-1: Analysis Input File Processor aborted due to errors. Error in job Job-1: Analysis Input File Processor exited with an error. Job Job-1 aborted due to errors. So, why is the set not defined or exported from HM? Where's my error? HM version is 14, Abaqus version is 2017. test.inp test.hm
  19. Hello everyone, I want to get stress/strain vs. time curve in hyperview, but I have only learned how to do linear static analysis in hypermesh. I try it in hypermesh, but I only get one point in the hyperview 2D plot as the picture shown. I want to know if there are any video or may you tell me how to choose those cards can I get the stress vs. time curve in hyperview. Thank you so much for you time. ~~(^_^)
  20. @Prakash Pagadala I changed it to analysis only later. It works now. Yes, you are right. Optimization is too big to run. This model contains about 3 million elements. Thanks again
  21. Hello Praniket I'm getting this same error. I'm a COEDAS student registered through Infaetek Institution. I have obtained the license but not the download link for the set up file. The license obtaining procedure was done by the Infaetek so i didnt register in Altair strore. Please provide a solution for this issue, thanks
  22. @harikrushna E and Nu are minimum requirement to form a stiffness matrix - technically... Theoretically- Nu defines the way material will change its shape. Hooke's Law
  23. Hi Prakash, Is there another method to set the Flux input to the entire plate (topology domain) ? As refer to the example above, that comes from attached paper, the optimization can be done by using Optistruct. Can I add heat flux to nodes/ elements without using CHBDYE ?

  24. Hi, Once the user profile is selected as OptiStruct, the HyperMesh interface is loaded for the same. The active user profile will be displayed in the top of the HyperMesh window. We cannot select OptiStruct from Applications menu and so it will be always grey. You can continue working after selecting OptiStruct user profile. Many video tutorials on OptiStruct are available at https://www.youtube.com/user/HyperWorksUniversity/search?query=optistruct . A simple tutorial and the model file is also attached for reference. Tutorial.pdf plate_hole.hm
  25. Have a look at .... Hooke's law of Elasticity Theory
  26. The case i'm studying is a front suspension dynamic analysis, but among standard templates there is front suspension and full vehicule. For full vehicule choices in task wizard are dynamic analysis while in front suspension there is only quasi statique and static analysis. My question is how can i perform dynamic analysis on a front suspension.
  27. Sir, In analysis software we have to input at-least E and U propertiess, But when we look in simple deflection formula (W*L^3)/(3*E*I), not required (poisson's ratio) why we have to input poisson's ratio?
  28. i used unit load on the load collector and assigned DAREA as load type
