Scan-and-Solve for Rhino

Simulate Early, Simulate Often... In Rhino


Good morning guys,

i need to figure out if this amazing software can be used to help us in our work. We manufacture storage tanks and we need to figure out how to determine the structure of the external reinforcement. The problem is that, with so simple a structure,with the calculation of the hydrostatic pressure, the software takes 20 hours to make the calculation? Probably I'm wrong in the set of operations or actually calculate it take so long? Any advice would be accepted. thanks

Francesco,  it is hard to tell without looking at your model and settings.  You may be running into high aspect ratio problem (see Large size to detail ratio  under limitations in documentation).   If you can post your model or send it to us at support@intact-solutions.com we can take a look at it for you.  

Good morning guys,

thanks for the reply.
From what I understand, my structure is apparently simple, but having a thickness of 4 mm, which makes it more complex to calculate, I got it right? If also add the external reinforcement calculation becomes even more complex. I'm not an engineer, so probably something wrong in setting the constraints and loads. Then I ask a question: the tank is obtained from the coupling of welded sheets, so if I tell the software that every weld is a linear edge restrain , lighten the calculation? Also, I can apply a hydrostatic load in kg / m3 on a model with units in millimeters?
Attached sending the file for you to better understand. Material is steel cast carbon.

Thank in advance for helping.

Sorry for missing file.

The file does not have the boundary conditions (restraints, loads).   It is impossible to tell what you are trying to do without them.

You are trying to analyze a >5m structure that is 4mm thick,  with solid elements.   A 5m x 5m square sheet is 25 million 1mm squares,  so this would translate into 25 million(!)  1mm^2 surface elements and 100 million (!)  solid elements, at 4 elements across thickness, for 1 such square.      This is the reason why such structures are usually analyzed using 2D elements.  Yes, Scan&Solve will give you an answer,  but you probably do not have the resolution and there is nothing simple about it.  You can turn on the grid display to see where your solid elements are.  

It looks like this is a second time you are asking essentially the same question.  See the previous response.   

Thanks for reply. In fact, one year ago I was exposed to a similar question and Michael told me that version of the software was not able to analyze the type of structure. I had to prove to my boss the usefulness of the software for our purposes. Follow the advice from Michael on how to proceed to get around it, it was not a good solution for us. I wanted to try the 2014 version better understood if we could analyze the structures as they are, without deleting geometries.
