Dear friend
This is my problem I need to calculate the pressure gradient along the axis of the artery model. (I did transient analysis on the artery model) how can i plot the graph (axial length vs pressure gradient) in cfx post I did the following method I drew a line along the axis then in the graph i set General>type>xy then Data series>location >line xaxis>variable >Z then Yaxis>Variable>pressure gradient Is the above method correct or not? Note:Transient analysis has been conducted. is the plot axial length vs pressure gradient indicates the last time step graph or accumulated time step graph Please help me Thank you Govind |

Seems right if you are trying to plot DP/dz. I assume you are not trying to plot DP/dt.

If you are getting your graph that shows pressure and length then you are doing it correctly. I usually check the "custom data selection" box and select my two variables. This will be data from whichever timestep you have selected (which is thew last results file unless you changed it) you can change the timestep by going up to the clock looking icon which lets you choose different timesteps.
You can only make a transient graph using points, not lines. You can export the data of any graph by clicking the export button You can also make an animation of the pressure by making a contour, then clicking on the animation button right next to the timestep selector, and clicking your contour and animate. You may want to set your contour to a fixed range for this. |
