Dear All
I am currently using Creo Simulate to analyse extruded aluminium framework (racks), used to contain electronic modules.
A rough idea of the size of a rack to be analysed would be 2.0m x 0.5m x 0.5m, divided into a series of horizontal slots used to contain the components.
The edges and corners are L shaped extrusions with corner brackets (generally 3-5mm profile) , with thinner (1-2mm thick) plates to create the 'sides' of the assembly.
The material is typically 5 or 6 series aluminium.
The models will be subjected to static or modal / random dynamic loading.
I am trying to set up a series of guidelines for design community such that the models can be imported into Simulate with minimum de-bugging (I have experienced many models which cannot be imported into simulate due to issues regarding tolerances / accuracies).
When the model has been meshed I also encounter 'element incompatibilities' and several geometry based 'warnings'.
I was wondering whether somoene could help me with some guidance on the 'accuracy settings' for the design of such models (in the Creo Parametric 2.0 domain).
File> Model Properties > Materials > Accuracy
There are Absolute and Relative options, and I believe the values entered are dimensionless.
I am trying to avoid a large re design of existing models such that they will run in Simulate, and also to suggest a set of 'ground rules' for the creation of new models, for the design community, but also for my own work.
Any basic thoughts or guidelines regarding the 'design' phase of the racks in order to create more accurate designs (and subsequent FEA models) would be appreciated.
Many thanks
RB.
