Q. The customer wants to define directionally dependent mass values (massx, massy and massz) for a point mass in Workbench.
Can this be done?
A. Yes. The point mass is a MASS21 element. It would involve using a command object to modify the MASS21 real constant properties representing the point mass.
Below is a sample script for doing this.
*****************

esel,s,ename,,21 !select mass 21 element of interest
*get,elem_num,elem,0,num,max !parameterize the element number
*get,r_elem,elem,elem_num,attr,real !parameterize the real constant number

Question:
I have a transient result file and I want to calculate the torque using the CEL torque function from cfx5post. I noticed that the torque is calculated using the pressure from the current time step. How is it possible to make the torque function to use the time-averaged pressure (Absolute Pressure.Trnavg) in order to calcute the time-averaged torque?
Answer:
Steps to calculate the time-average torque in CFX-Post (Example axial rotor stator tutorial)
1. Create an expression for myTorque (Torque_z()@R1 Blade × Number of Blade)
2. Create an additional variable, myAV torque
Variable Type: Specific
Unit : N m
Tensor type: Scalar
3. Set in the rotor domain the additional variable
myTorque
Type: Algebraic
4. Set the transient statistic option
Output ? trn Stats ? New
Option : Arithmetic Average
Output variable List: myAV torque
5. After simulation you would have a new CFX-Post variable (myAV Torque. Trnavg), at the required loaction (in this case at the Rotor blade) |

Q. A shell element plot appears to be hollow inside when plotted with thickness included (/ESHAPE,1). The problem occurs when plotting elements in the transition between two areas, possibly also in the transition between the real constant sets. Is this a code defect?
A. This is a limitation to /ESHAPE,1 graphics when shell thickness is defined with a real constant set. The workaround is to use SECTION data to define thickness instead. The plan in future release (possibly 13.0) is to not support (undocument) the use of real constants with the latest shell element technology. |
