I am catering 16km TBM Tunnel, and I have two main issues.
1. Length of the tunnel discovers GC limitations. Computing tunnel build from rings (ring is created as node element build from build from 7 segments) takes 12 minutes for 1km distance on fast computer. It is impossible to create full 16km length ,hence model has to be split. Is there other solution for that? And is there a plan for multi core CPU support?
2. Creation of Key Block or Segment from WALL. Key element looks like on picture below
For normal Segments (C shaped) I am using Wall node created on arch. No problem here. I am using wall as I need to have all project metadata from catalog.
Problem is with key element. I have to cut (node Wall by cut) C shape segment on both side, by rotating two planes at the end of the segment. I use line as cut tool and feeded to CuttingProfile makes the software crash. When I do not rotate planed I see some cut preformed - but software again fezzes and crash.
Is there a better way to created tunnel key element (tapered C shaped wall) from Wall than by cut?
Software version as required on the project:
ABD SS6 08.11.06.866
16km tunnel length exceeds the recommended Solids Working Area (~volume) so we would recommend splitting the model.
I'll ask a colleague who has been looking at GC in tunnelling to comment further on the key segment question.
Thank you Marc.
Yes, SWA is my other worry.
I created normal Aecosim solid model (with metadata from Catalog) and it works quite well at the moment.
We can cut it along whole length with no big issues (at the moment).
Could you please clarify which application you are using for the creation of the tunnel liner segments? Are those modeled in AECOsim Buildings Designer or with GenerativeComponents nodes? If you are using GenerativeComponents, would you mind posting the script or sending it to Volker.Mueller (at) Bentley.com.
Please note that we have worked on GenerativeComponents since the last V8i release almost three years ago. All that work, however, has been applied to and made available in CONNECT Edition releases, with latest release being CONNECT Edition Update 5. Especially in the past year we have invested a lot of effort in performance improvements. As mentioned before, the benefits of that development work are available only through CONNECT Edition.
I do understand that project constraints may limit your flexibility in selecting software versions. However, that also limits how much we can help you with our innovation.
Solid operations in AECOsim Buildings Designer and also in OpenBuildings Designer are limited to the Solids Area, with an additional constraint for dynamic views. Solids might be additionally constrained to a 1 km cube. We have started renovating solids modeling in GenerativeComponents. Again, any progress in that area will be available only in future updates of CONNECT Edition.
Meanwhile we can look at strategies to proceed with your work in the software version that you are required to use.
Let's start with the tunnel liners as suggested in the first paragraph of my message.
Hi Volker, very informative replay, thank you.
I create segmental Ring in GC (ver 08.11.09.436 - Extension for V8i SS6 08.11.06.866) as a node and this node is used later for replication and rotation along alignment in other file. Ring Node is build from 7 arches, and from those arches I create 7 curved Walls (Wall fromArc). Unfortunately my node was created in training file, and there is a lot more code then just Ring. I will try to create simpler example.
Good point regarding software version. I will check on the project if I will be able to use CONNECT Edition.
