SubscriberHi,
I have an assembly having parts with the following widths in mm, as shown in picture. I performed Static structural analysis in Workbench.
Now I want to do a comparative analysis with DL 2020 R1. It is showing that at 100% fidelity settings the minimum length it can capture is 1.9 mm. 90% of the geometry has width <1.5 mm.
The maximum v-m stress that WB can capture (as a shell model) is 100 MPa while in DL is around 300 MPa at this setting.
I am using NVIDIA P1000 4GB GPU, with shared Intel GPU of 16GB.
I want to know
1. If I run on a system having higher GPU will it be able to capture more lesser geometric lengths (at least 1.2mm) at 100% fidelity and
2. Will it improve the accuracy?

SubscriberHello Biraj Dey ,

You are correct. If you are working with the highest fidelity, and if Discovery LIVE still ignores the features, there are two things you can do (which is also explained in detail in this post),
- Get a larger graphics card (more memory and faster clock speed) - This will allow you to simulate larger problems with more detail.
- Simulate a smaller problem - See if you can split the model into smaller regions and apply appropriate boundary conditions to those smaller regions.
This query thread also discusses the same issue.
I am using NVIDIA P1000 4GB GPU, with shared Intel GPU of 16GB.
Here is a list of known Discovery Live friendly GPUs or Graphics cards and general hardware requirements to run Discovery LIVE or EXPLORE.
Will it improve the accuracy?
Discovery Live is intended for early concept refinement and should never be used for final validation or certification of a design. Although the attached benchmarking study provides a sense of Discovery Live’s capabilities and accuracy (which depends on the GPU capabilities).
Regards.
