To show the results in a contour plot, go to Plot > Contour/Multi-Coloring and select the Velocity Magnitude as your contour variable. Under Convective Variables, Select the Velocity option, click the Select button, and choose the velocity variables, where U, V, and W, are the X, Y, and Z components of velocity, respectively.Ĭlick the Select button, select Velocity Magnitude from the list, and click OK After loading your data, do the following: In this method, the velocity magnitude calculation is performed by the CFD Analyzer and the calculated result is stored in a new variable. Using the CFD Analyzer (only works in Tecplot 360) The W term should be removed for 2D velocity magnitude calculations. This article describes both a macro and a PyTecplot script that extracts a field variable along a line normal to a surface. Be sure to change U, V, and W to match the variable names of your dataset’s velocity components, as defined in Data > Data Set Info. Macro, Pytecplot, Tecplot 360 September 27, 2019. **2)Ī text string enclosed in curly braces defines a variable name.

Now I want to use Tecplot software to draw some velocity profiles (X-axis is the diametry, Y-axis is the velocity magnitude. The caculation had be finished in Fluent 6.1. This gives the average normal velocity going through the isosurface for a single zone (one time solution) or you can calculate it over a time strand.Alter > Specify Equations and enter the following equation: Hi everyone: My model is a pipe flow with one inlet and two outlets, which diameter is variable with the flow direction, and there is a symmertrical plane at Z0 and XY-plane. This is the integral in the denominator of the equation above.Ĥ) Then, in order to find the average normal velocity to the iso-surface, manually calculate the following: Divide the “Vector Dotted with Unit Normal” integral from step 2 by the “Length/Area/Volume” integral calculated in step 3:Īverage Velocity in Normal Direction Through Iso-Surface = (VectorDotNormal) / (Area) You can view these vectors by following the procedure in the section “Surface Normal Calculations” in the User’s Manual.ģ) Calculate your second integral, the surface area of the iso-surface with the “Length/Area/Volume” integral. Note: The normal vectors are calculated within the integration function, but the direction of these normal vectors must be verified.plotted for presentation using Tecplot 360 (Tecplot, Inc., Bellevue WA). Integrate by the extracted iso-surface zone or time strand. In an attempt to get improved images, the plastic model was subsequently imaged. For calculating the velocity normal to the surface of the iso-surface, we will use the variable components of the velocity vector in our data set, in this case: Vel_U, Vel_V, and Vel_W.It is the integral of the numerator in the equation above: Vel_U, Vel_V, and Vel_W). We will start by calculating the “Vector Dotted with Unit Normal,” as described in the User’s Manual. This example only requires the convection field variables to be set (e.g. You can also do the same by define a profile on the edge and write the values. You then extract the values in Plot, XY plot, there you can write to file.

Review the tips in “Performing Integrations” section of the User’s Manual and make sure you have the appropriate Fluid Properties…, Reference Values…, and Field Variables... as required. you can create a line in surfaces or use an edge you already have defined. Make sure the iso-surface in other solution times are assigned to this time strand by going to Data –> Edit Time strands….Ģ) Now it is time to calculate our integrals.
