Numerical Simulation of Vortex Shedding at Triangular Obstacle for Various Reynolds Numbers and Times with Open

Figure 4- Flow lines and velocity vectors for different mesh sizes at Reynolds number 35

multi-faceted cells are attributed to each non-structured
three-dimensional mesh. Residuals usage is one of the
methods to estimate error in solving the governing equations.
During the modeling, the aforementioned values are
calculated by the model and displayed in the terminal. Finally,

Then, by writing name of the solver in the terminal, modeling
started and the results of solving steps such as the Courant
number, residual, and accuracy of convergence were seen in
the terminal. This model uses the finite volume numerical
method to solve partial differential equations, in which
