White Paper: Simultaneous Durability Assessment and Relative Random Analysis Under Base Shake Loading Conditions
For many automotive systems, it is required to calculate both the durability performance of the part and to rule out the possibility of the collision of individual components during severe base shake vibration conditions. The check for “collisions” has previously been done separately with the resultant “doubling up” of the analysis being both time-consuming and cumbersome. However, new technological advances now make it possible to do both these calculations at the same time and this paper will present results for an exhaust model analyzed using NASTRAN.

White Paper: Creating Accurate Surrogate and/or Accelerated Loads for Known Models or Structural Systems Types

Two common approaches are currently used. This paper presents the details of a new approach which is a variation of the FDS approach but using the actual system properties.

Materials and Material Management
When simulation results don't make sense, what checks do you perform? Besides the modeling aspects of loads and boundary conditions, mesh sizes, right formulations, etc., the most often overlooked cause of problems is the wrong assignment of materials and properties in a solver input deck. In the midst of running many simulations it is so easy to modify values that users forget that what they intended for a part is not what is being analyzed. Identifying the correct material values and assigning them is such a crucial step in your analysis that any mistake can compromise the results and design decisions you make based on simulation.
