Help Needed: STKO Closes Suddenly When Viewing Fiber Damage Results

[Farazchanna]

Hi STKO Team, I am working on a non-linear model and I used the ASD 3D command to model a shear wall. I applied a half-sine input to observe its behavior and to identify the parts with more damage and cracks. All the plots opened without any issues. The problem is that my output file size is too large 1.9 TB. Even with a smaller file of 166 GB, when I try to open the fiber section plot, STKO freezes and hangs. The same issue occurs even when I use a smaller time step. I have the paid version of STKO, so I am not sure what the issue is. Please help me fix this. In Video 2, I only recorded two results: displacement and section fiber damage. The output file is 20 GB. I used a 2.5 sec input with dt = 0.0025. However, the same problem occurs. When I click on the "Fiber Color Map", STKO closes suddenly

I don't need the video, please share the model?

Hi, sorry for the late reply. This is my complete research. It is a fixed-base model with a height of 238 meters for an existing structure located in China. It is fully non-linear and includes over 950+ beams, more than 10 types of composite columns, 20-30 types of simple columns, and 3 different grades of shear walls. I used C30, C50, C55, and C60 for concrete and three different grades of steel.

I will share it, but this is a public forum and everyone can see it. Could you please delete the file from the forum after you have seen it? I would really appreciate that favor.

Thanks again. I look forward to your reply.

ok so, before sharing the model, let's see if it's a Graphic issue or memory issue.

First: are you using a laptop with a dual GPU? like an integrated one and a high-performance dedicated one? If so, make sure you are using the dedicated one.

Second: How many fibers are you using in your fiber section? Saving results on fiber sections requires a lot of memory if the fiber section are very dense and the model is huge

Dear STKO Team,
Thank you for your reply.

Regarding your questions:
1. Hardware Setup:
I am using a desktop workstation equipped with an NVIDIA GeForce RTX 3090 (24 GB VRAM) and 256 GB System RAM.

2. Model & Fiber Sections:
Columns: 20–30
Beams: Over 950
Shear Walls: 80- 90, layered shell (ASDConcrete3D material).

Looking forward to your guidance.

Hi, Could you please share your email address with me? I will send you my model, as I think it will be easier for you to understand the actual problem.

Please send the model to [email protected] with a little description referencing this forum post
