Hi, I am using ANSYS APDL for modelling a bridge under flood hazard. I am stuck at a point where I am unable to feed the flood load in terms of the flood velocity without actually calculating the flood load for each and every velocity values as given in AS 5100 formulas. One of my friend told that I can create some macros in ANSYS APDL and thereby feed velocity values straight way without calculating the flood load repeatedly for different flood velocity values. Can someone please help me?
For instance the code defines the flood force as below
F = 0.5 Cd * V^2 * As.
I am trying to create a macro or give a command to the ANSYS software to include the above formula into the system so I can directly feed velocity, Cd and As values for the software to calcualte the force value
Hi, I also faced the same problem before. But instead of macro I tried a different approach which also works fine. With regard to your specific formula for F = 0.5 Cd * V^2 * As, try doing this.
-Go to your root folder of ANSYS save database which is by default C:\Users\Your PC name
-Make a new txt file named something called mac.txt and type the following code snippets and save it
*ASK,Cd ! ASK command in case you want ANSYS to prompt for dynamic input
*ASK,V
*ASK,As
F=0.5*Cd*(V*V)*As ! Don't type V^2
-Come back to ANSYS and whenever you want to use this particular function of F, type \INPUT,mac,txt.
I hope this helps.
Are you looking for making a loop so that you "automate" calculating the flood load per each velocity..etc? If that's what you want, either create loops ( like *do loop) inside the APDL or create a macro, indeed, inside the apdl ( like the segment you want to repeat, start with "macro" ...put your code, then "end macro". OR you can save the macro code into a separate file and call for it. On either situation there is no escaping from making *do, loops inside the apdl.
