Dear lists,
This is Rajesh, I am using equest from 6mnths. I need know system requirement, for equest when have to model high rise building. Actually, when I model fifty storey building, & run the BDL, atlast it comes out to insufficient memory, & it gives errors. I use floor multiplier to reduce load on PC. My PC configuration is intel dual core processor, with 4 GB RAM. If I have to upgrade my pc, then what would be its configuration. If I have to buy a server, then is it possible that equest will run on it. If I have to model a 100 storey building, kindly give solution. I would greatful for the solution.
Thanks & Regards.
Rajesh Guda

You should have plenty of capacity on the PC you described. I would check your model - are you sure you have floor multipliers on?
As an aside - I just did a quick run of a 100x100 floor plate with 50 storeys - and it ran fine - straight out of the wizard - even with the floor multipliers on. I have a laptop - intel i5 processor with 6GB ram, but I think it would have run on a slower computer too.
Check your other settings.

I would expect that computation time would slow considerably with
this scenario. Not only do you have 2 high rises to run but you also
have the shading interaction with the 2 buildings. This is a good
approach. From a work efficiency point of view and easier trouble
shooting it would make sense to start your model with one building.
Create a base model up to the point you have major deviations in the 2
buildings. Make 3 copies, and go forward with each building and have
one copy as backup. I normally spend a lot of time at the edge of the
DD wizard and the DD edit fixing problems and making sure the model is
running correctly before going into the DD edit. This will allow you to
troubleshoot each building separately and then once the buildings are in
the same model all that has been added is the interaction of the 2
buildings as shades on each other.
I think a big mistake new users are making is not progressing along
a logical building and troubleshooting path when creating their models.
If you deal with each stage discretely it limits the number of errors to
troubleshoot and places to look for them. It is a more efficient use of
your modelling time in the long run. It also breaks your time
investment into stages as well. There is nothing worse than getting 15
hours into a model, have a critical error and have your file disappear
into cyberspace. Almost as bad, is to have 2000 error messages and
trying to figure out where to start. There may only be 10 real errors
but a basic error is like a chain reaction through the whole run and
will generate a multitude of associated errors. If you are lucky and it
runs that long.
Sorry for the drop on the list, seems my email send configuration was
improperly adjusted.
