Output Graph
Type:

bool

Value:

True or False

Usage:

Required

Description:

Output the Panzer graph. Useful when debugging.

1    <Parameter name="Output Graph" type="bool" value="false"/>
Workset Size
Type:

integer

Value:

\([0;\infty]\)

Usage:

Required

Description:

Set the workset size as defined by Trilinos. On CPUs, the workset size is typically set to 256. On GPUs, the workset size is set to larger values (1000-4000). Note that the workset size is machine/problem dependent. It is recommended to perform a sensitivity of the solver to the workset size for optimal performance.

1    <Parameter name="Workset Size" type="int" value="256"/>
CFL
Type:

double

Value:

\([0;\infty]\)

Usage:

Optional

Default:

None

Description:

CFL condition for transient solver.

CFL_init
Type:

double

Value:

\([0;\infty]\)

Usage:

Optional

Default:

CFL value

Description:

Initial value of CFL condition to use when ramping CFL.

CFL_transition
Type:

double

Value:

\([0;\infty]\)

Usage:

Optional

Default:

0

Description:

Number of time steps to ramp the CFL condition over.

1    <Parameter name="CFL" type="double" value="100"/>
2    <Parameter name="CFL_init" type="double" value="0.1"/>
3    <Parameter name="CFL_transition" type="double" value="100"/>
Gravity
Type:

array(double)

Value:

Vector of real value

Usage:

Optional

Default:

None

Description:

Gravity vector.

1    <Parameter name="Gravity" type="Array(double)" value="{0.0, -9.80665}"/>
Wall Names
Type:

string

Value:

List of side set names.

Usage:

Required if using Spalart-Allmaras, K-Epsilon, and K-Omega SST turbulence models.

Default:

None

Description:

List of side set names to compute the wall distance from. Names are separated with commas (e.g., “wall1, wall2, wall3”) and must be the same names as defined in the mesh file. This input parameter is needed by the WallDistance closure model.

1    <Parameter name="Wall Names" type="string" value="top,bottom"/>
External Magnetic Field Parameters
External Magnetic Field Type
Type:

string

Value:

“constant”, “toroidal”, or “x_tanh”

Usage:

Optional

Default:

“constant”

Description:

External magnetic field type for MHD simulations.

External Magnetic Field Value
Type:

array(double)

Value:

Vector of real value

Usage:

Optional

Default:

None

Description:

External magnetic field value for MHD simulations.

1    <ParameterList name="External Magnetic Field Parameters">
2      <Parameter name="External Magnetic Field Value" type="Array(double)" value="{0.0, 1.0, 0.0}"/>
3    </ParameterList> <!-- External Magnetic Field Parameters -->
External Magnetic Field Time Rate of Change
Type:

array(double)

Value:

Vector of real value

Usage:

Required with External Magnetic Field Type = constant

Default:

0.0

Description:

External magnetic field change rate, \(\vec{B}_{dt}\), in the expression of \(\vec{B} = \vec{B}_{input} + \vec{B}_{dt} t\), where \(\vec{B}_{input}\) is the initial magnetic field value and \(\vec{B}_{dt}\) is the rate of change.

Toroidal Field Magnitude
Type:

double

Value:

\([-\infty;\infty]\)

Usage:

Required with External Magnetic Field Type = toroidal

Default:

None

Description:

External magnetic field value in toroidal direction for MHD simulations. If the external magnetic field type is “toroidal”, this parameter is required rather than the “External Magnetic Field Value”.

External Magnetic Field Distribution Offset
Type:

double

Value:

\([-\infty;\infty]\)

Usage:

Required with External Magnetic Field Type = x_tanh

Default:

None

Description:

This parameter sets the offset, \(\beta\), in the distribution given as \(\vec{B} = \vec{b} (1-tanh(-(x/\alpha-\beta)))/2\), where \(\vec{b}\) is the maximum external magnetic field value and \(\vec{B}\) is the x-varying external magnetic field value.

External Magnetic Field Distribution Curvature Coefficient
Type:

double

Value:

\([-\infty;\infty]\)

Usage:

Required with External Magnetic Field Type = x_tanh

Default:

None

Description:

This parameter controls the curvature of the distribution. This corresponds to \(\alpha\) in the distribution given as \(\vec{B} = \vec{b} (1-tanh(-(x/\alpha-\beta)))/2\), where \(\vec{b}\) is the maximum external magnetic field value and \(\vec{B}\) is the x-varying external magnetic field value.
