ANSYS Ansoft (Maxwell) - Additional Information
What is Maxwell?
Maxwell is a simulator that allows the user to create an accurate, two dimentional representation of the electric or magnetic field behavior. And obtain important data such as forces, torque, induction, etc. This software is use mainly by the Electrical and Computer Engineering Department.
How to Start Up Maxwell
In order to start up Maxwell, these following line have to be add to the .cshrc file:
if ( -e $SOFT/ansoft) then
source $SOFT/ansoft
endif
Then " source .cshrc " file. Then at the Unix promt type
maxwell
to start up the software.
What is HFSS?
Hfss is used to design on-chip embedded passives, IC packages, PCB interconnects, antennas, RF/microwave components, and biomedical devices.
How to Start Up HFSS
In order to start up hfss, these following line have to be add to the .cshrc file:
if ( -e $SOFT/ansoft) then
source $SOFT/ansoft
endif
Then " source .cshrc " file. Then at the Unix promt type
hfss
to start up the software.
How to Run Maxwell, HFSS in Background
In the engineering labs, Ansoft is installed in /opt/soft/ansoft-*. If you would like to solve two projects remotely which are both in your home directory with the names horn and waveguid, the file names would be horn.hfss and waveguid.hfss. Where horn.hfss has multiple designs e.g. design1, design2, etc and waveguide has a single design.
1- Prepare the two projects up to the point where all that remains is clicking the 'Analyze' button. Save your project and exit from the software.
2- Go to your home directory and create a shell script, call it 'file.run'.
3- Connect to any of the Linux servers provided by DECS and type 'source $SOFT/ansoft'
4- You need to know and record the full path for hfss executable, therefore, type 'which hfss'
e.g. /opt/soft/ansoft-12/hfss12/hfss
5- The file, file.run, is to contain the following lines where 'home' is the absolute path of your home directory and /opt/soft/ansoft-12/hfss12/hfss is the absolute path of where hfss is installed for the Engineering labs:
/opt/soft/ansoft-12/hfss12/hfss -ng -batchsolve design2 /home/USER/horn.hfss
/opt/soft/ansoft-12/hfss12/hfss -ng -batchsolve /home/USER/waveguide.hfss
The first command will only solve 'design2' in horn, the second command will solve all designs (if available) in waveguide. Consult, hfss documentation for more command line options.
6- Make the file, file.run executable with the command, 'chmod 700 file.run'.
7- Execute file.run in background on a server with the command 'nohup file.run &'.
Note: if your design is huge it is better to use /egr/scratch instead of your home directory.
Features in Maxwell
- Simple, easy to use graphical interface.
- Automatically calculate executive parameters such as forces, torque, etc.
- Integrated electromagnetic field calculator
- Simulates the full range of eddy current bus bars, transformers, ect.
