ahad,
I hope this information about control number of elements (in INTEGRATED MODE) could be usefull, I took this information from PTC Knowledge Base Site.
Suggested Technique for Preparing Model
In Pro/MECHANICA Structure and Thermal, elements need to be generated in the part or assembly as the first step in the analysis. In Integrated mode elements are automatically created using AutoGEM as part of the analysis. In most cases AutoGEM will complete a properly built model without any user intervention. In certain situations, including models with geometric inconsistencies or small features, AutoGEM needs to be assisted in order to successfully complete the mesh.
Procedure
1. Surpress all unnecessary features - this will reduce the total number of elements generated and may also simplify the geometry to a point where AutoGEM is able to mesh it successfully. It is especially important to surpress features which can create small or difficult to mesh surfaces. Features likely to create these surfaces include; rounds, unaligned features and variable section blends and sweeps.
2. Check the following items inside of Pro/ENGINEER to ensure that the geometry is fully specified within Pro/ENGINEER.
Info, GeomCheck - Highlights any geometry with unclear Pro/ENGINEER design intent. All GeomChecks must be cleaned up for successful AutoGEM.
Analysis, Surface Analysis, Slope - colors the part according to surface slope. This allows easy determinition of whether or not edges are sharp and also ensures that geometry changes are smooth in blends and sweeps.
Analysis, Model Analysis, ShortEdge - highlights small edges
Analysis, Model Analysis, Global Inteference - highlights any areas of interference for assemblies. Interference should be avoided in assemblies that will be meshed with solids. Interpenetration can be a useful technique for lining up mid-planes in shell compressed models and will work in the majority of cases. In a small number of cases, interference in shell compressed assemblies will create incorrect geometry. Because of this, interference should be removed when trying to debug AutoGEM issues on shell compressed assemblies.
3. Modify the model to clean up any geometry which appears questionable. In cases where small surfaces or edges with rounds create problems, the commands Tweak, Replace; Tweak, Patch; and Protrusion, UseQuilt may be useful. Adding sections to blends and sweeps and adding points in variable radius rounds may be helpful.
Regards!
