Geometric Surface Element Form	CHBDYE,CHBDYG, CHBDYP	SOL 153 Steady State Nonlinear Heat TransferSOL 159 Transient Nonlinear Heat Transfer	Lets you specify the bulk entry to use to define a boundary condition surface element for a SOL 153 analysis.
Purpose
Random Base Excitation Event	-	SOL 103 Response Dynamics	When you select thic check box, the solution is validated for use by a Random Base Excitation Event using Simcenter 3D Response Dynamics. Furthermore, this option modifies the solution for computation by the Random Base Excitation Event for failure metrics and usage of any residual vectorsFor more information, see Simcenter 3D Response Dynamics.

Run Job in Foreground	-	All solutions	Lets you control whether to run the solve in the foreground or background.If you select this check box, the solve runs in the foreground and you cannot use the software until the solve is complete.If you clear this check box, the solve runs in the background. You can use the software while the solve is running and can even close the software.
