Simput - PyFr - euler-vortex-2d

Instructions to recreate euler-vortex-2d.ini in Simput. Unless mentioned below do not change default values.

Constants

• delete cpTref
• add three custom constants,
  • S = 13.5
  • M = 0.4
  • R = 1.5

Solver

Settings

• order: 3
• set Viscosity Correction to nothing
• set Shock Capturing to nothing

Time Integrator

• initial time = 0.0
• final time = 50.0
• time step = 0.005

Interfaces

• delete LDG Beta
• delete LDG Tau

Solver Interfaces

• change Type to Linear

Solver Elements

• Add one, change nothing

##Solution For each of these sections add an item and change the type to the section's name. Rename the property in the sidebar if desired.

Plugin NaN check

• nsteps = 50

Plugin Writer

• disk write time interval = 10.0
• basedir = .
• basename = euler_vortex_2d-{t:.1f}

ics

• Initial Density = pow(1 - S*S*M*M*(gamma - 1)*exp(2*%(f)s)/(8*pi*pi), 1/(gamma - 1))
• Initial X velocity = S*y*exp(%(f)s)/(2*pi*R)
• Initial Y velocity = 1 - S*x*exp(%(f)s)/(2*pi*R)
• Initial static pressure dist =
  1/(gamma*M*M)*pow(1 - S*S*M*M*(gamma - 1)*exp(2*%(f)s)/(8*pi*pi), gamma/(gamma - 1))
• add a helper function: f = ((1 - x*x - y*y)/(2*R*R))
