Adaptive mesh technique for the simulation of a forming metal sheet component.
The provided model showcases the forming of a metal sheet component. Adaptive meshing technique is used to improve the results of the simulation, while minimizing the number of elements and, hence, the cost of simulation. Altair® HyperForm® has been used in order to set this model up. The model overview is displayed in…

Error loading state file: File .sta not found. When solve multistage in Radioss incremental
Hi everyone I have an error case when I try to practice HF-3020: Setting Up a Multistage Simulation with the User Process. I make sure I set up the same with instructions. But always have an Error loading state file: File .sta not found (picture 1). It solved normally in stage 1, but when finished it did not create a .sta…

Prompt window shut down while performing HyperForm forming analysis for composites
Greetings, I have already completed the tool setup for the model I'm currently working with, but whenever I try to run the compression molding simulation analysis inside HyperForm, the black window prompt opens and shuts downs immediately right after - only two .rad files are written and no animation file is generated.…

What does the actual forming speed under thermal section of thermoforming means in HyperForm Radioss Incremental?
There is filed inside thermal section that ask for 'Actual forming speed' but I have already defined the velocity under the load section as the velocity of puch. Why is there two forming speed input field?

Which material law works the best to define the unidirectional prepreg tape in thermoforming simulation.
I am using the Hyperform environment in Hypermesh to perform some thermoforming simulations with unidirectional prepreg tape. I am having trouble properly defining the material properties. Since material Law 12,14,15,19 and 25 all are for orthotropic materials, I tried to use Law 58 but the warp and weft direction…

%thinning for solid blank
hi, I'm using HyperForm for solid forming simulation. I faced a problem that cannot see the thinning percentage result for the solid blank like below: Meanwhile, I found this information in HyperForm 21.1 release note: Can anyone explain to me? Thank you!

[Shell Model] Is clearance (gap for the blank to flow) between die and punch required while performing a shell model deep drawing simulation?
I am performing a deep drawing simulation on Hyperform Radioss Incremental with shell (surface) models of the components. It is known that a shell model doesn't have geometrical thickness (the thickness is assigned in the property manager). Hence, I have assigned a blank thickness of 2.5 mm, and make the rest of the…

In deep drawing simulation with shell model, is clearance between die and punch required?
I am performing a deep drawing simulation on Hyperform Radioss Incremental with shell (surface) models of the components. I have assigned a blank thickness of 2.5 mm. What I need to know is that whether or not Die-Punch Clearance is required in the shell model as if it is like solid model. Thanks in advance!

How can I compartmentalize a sheet metal blank into different rolling directions (angles like 15, 30, 45, 60, 75, 90...degrees) on Hyperworks?
I'm undertaking Deep-Drawing simulation with radioss incremental solver. The sheet blank is anisotropic material and have different properties in different rolling directions. I want to observe the strains in these directions. You can check the attachments. Thanks in advance.

Error ID 55
Hello, I have a question regarding constraints to run a springback calculation. I had a blank in the form of a cylinder which I formed using cone shaped tools (see image below). I am trying to run a springback simulation with the center of the cylinder blocked but I am getting the following error: ERROR ID : 55 ** ERROR IN…

How can I end my simulation with a condition on Hyperform?
Hello, I am working with Hyperform version 2017 and I have small question regarding simulation conditions. I want to form a cylindrical blank using 4 tools (2 on each side of the cylinder). The tools move symetrically. The problem is, I want the simulation to end once the blank touches (circled in red) the 2 tools on the…

Why is my Radioss calculation stuck on one frame increment for a very long time?
Hello, I have been trying to run a stamping simulation for a couple of days but it seems the calculation doesnt want to go further than frame 16. I have verified the tools and blank, the elements, the gap between the tool and blank as well as the friction and speed and I cant figure out the reason as to why. Please see the…

Simulation results interpretation
Hi all, For a multi stage cylindrical deep drawing simulation I used a quarter of whole model to speed up the process. Attached is the final frame of 6th stage. In this photo I have used symmetry to show the complete model. As you see just on symmetry planes (xz and yz) there are some inconsistencies for thickness which…

Result from HyperForm Optimization
Hello everyone. I'm using HyperStudy with HyperForm to run the optimization for my stamping model. i found a problem that the result in HyperStudy report is different from the result that can be seen in HyperView.

display "auto process" in window instead of panel
hi everyone, i'm a HyperForm user. HyperForm is quite good and efficient. However, i feel very uncomfortable when using 'auto process' in HyperForm. Since the layout of 'auto process' is panel >> this make the graphics area becomes extremely small. <?xml version="1.0" encoding="UTF-8"?> i have change the settings in…

[Solved] Error 595 when importing .sta file
hi everyone, I have found a problem when doing the multistage forming simulation with HyperForm. Normally, we usually define the blank of a stage with the .sta file of its previous stage. We done this by using user process >> blank >> from file: with this method, HF works fine. However, when i use the 'import' tool in…
