  1. I ran a simulation and solver crashed with following error message. What does it mean? Simulating extrusion of a single hollow profile *** INTERNAL ERROR PH155MEMPAK Maximum memory used: 2157101 KB This error can come due to following reason, 1) If mesh in bearing and profile component is bad. Check if mesh in bearing and profile component is properly dragged in the extrusion direction. 2) if Freesurface start location in .hx is not defined correctly. How to overcome? Option #1: Check mesh in Bearing and Profile component. if you are running polymer extrusion then check mesh in Land and Profile component. Check if mesh in bearing and profile component is properly dragged in the extrusion direction. Option #2: check what is start Z location of Bearing solid open .hx file and review value for Freesurface pset variable. it should match bearing start Z location.
  2. Hi Pradeep, We changed the starter file extension from .tcl to .hx. You should refer to *.hx file. Interface will write .hx and .grf file. Also to launch solver, please use HW Solver launcher from start menu as shown below.
  3. Hi Cbertoli, These are advanced topics. We can certainly help you with this. Can you please provide your contact information. One of our support engineer will contact you.
  4. I do not know what "vtk. file" mean. Can you please elaborate. Solver allows to saveresult as ASCII file ( text file) - not sure if you are looking for this?
  5. Hi D. Kramer, Which version of HyperMesh you are using? Please use extrusion wizard to set up the model. Extrusion will help you set all data automatically. The images you sent has data conflicting hence you run is not going as expected. Also, you show comment from ydigit, Our new interface Inspire Extrude/Click2Extrude will help you even further. there is no need of meshing. Please let me know us know your contact information, one of our support engineers will contact to upgrade your installation.
  6. Hi Chetankatam, You can do extrusion testing. Can you please explain the compression testing with a sketch? So that we understand the process.
  7. Hi Chetankatakam, if you mesh the entire flow domain of material #1 and Material #2 then you can do it. you will have to define Fluid-Fluid Interface between Material 1 and 2 . Initially, you will have to approximate thickness of final profile for meshing purpose. When you run the simulation, depending on material properties, flow behavior, the interface between two material will shift and you can get an overall idea on how the thicknesses will change. This is advanced support topic, if you are current HW/SolidThinking customer then please contact our regional support team for more details.
  8. Please elaborate you question. We can not access you model file.
  9. Hi Saiful, We did not get you model file. Looks like it got blocked.
  10. Is it possible to perform a transient tool deflection in HyperXtrude/C2E ? ==> No. Only steady state is supported. You have to use the older approach of Coupled analysis in which you have to mesh WP and tool in one model and run the coupled analysis. This is supported in the older interface. f a calculate the coupled solution in C2E It only has deformation. Temperature mapping is planned for future release and not available today.
  11. Hi Chiara, I know why differences. Let me first elaborate you on methods of performing coupled analysis, 1. simulating WP + tool mesh using HyperXtrude solver. This is older approach and is supported in old interface on HyperMesh. you are doing this simulation hence you are getting .fem file. This .FEM file already has correct loads and temperature from flow analysis. But in this simulation, we do not take back tool deformations to HyperXtrude solver and rerun flow analysis. 2. Simulation WP and then tool separately but the connection between both simulations is tightly related. This is supported in new Inspire Extrude interface which you do not want to use as it is fully automated and you do not have control. In this approach, we first perform flow analysis using HyperXtrude. Then send loads from flow analysis to another solver - OptiStruct to perform tool deflection analysis. Once the tool deflection analysis is completed, we take the deformation information and send it to HyperXtrude. Then HyperXtrtude solver takes the deformation consideration in flow analysis and continues the flow analysis. Hence the results will have the effect of tool deformation. This is also called HX-OS coupled simulation. If you are interested in getting accurate nose cone deformation then you should use approach #2 i.e. Coupled HX OS analysis. since we are performing flow and tool analysis separate, you see Tool deformation flag turn off in .out file as you mentioned in your previous comment. If you have further questions then please let us know.
  12. Hi Shawn, Question #2: "Seems to have a lot of bugs to report." Answer: Please let us know what issues you are facing. Python windows that you see are not for debugging purpose and we do not recommend our extrusion customers to open it. Inspire Extrude does lots of automation ( geometry cleanup, automatic mesh generation, mesh clean up, BC creation, solver export) in background hence model has to adhere to CAD the guideline for extrusion.
  13. Hi Shawn, Questions #1: "Material text seems to be editable in property editor" Answer: We do not recommend to change material from the property editor for Inspire Extrude. Thank you for reporting. We will inform this to our development team.
  14. 1. Can you please confirm if you have tried all training models? 2. Can you please confirm which version you are using? Latest version is 2018. Your model is working with 2018. I have not tried in older version.
  15. Dear Miezan, Have you tried training models? When you are learning Click2Extrude, it is strongly recommended to first try tutorial models. These are available in Help document. Press F1 key on key board. I checked your model, the solids organized not as per requirements. 1. Polymer die assemblies are made of stack/series of steel plates. They are placed one after another. 2. Hence, our workflow is geared towards this assumption, you should have series of die plates - placed one after another. 3. when you extract flow volume, Click2Extrude will automatically extract solids from each die plate and name them as Plate1, Plate2, .. and the last plate is assembly where polymer takes final shape is called as Land plate; hence last solid is named as "Land" 4. then you go and extract profile solid Issues in your model: You have entire bar and nozzle named as Land. But it should have been sub dived as shown in image below. I have corrected the model and please try with that. nozzle_corrected.stmod
