TopographyΒΆ

include_topography

  • Optional: Yes

  • Type: Yes or No

  • Description: Whether to consider topography in the simulation. This is an optional parameter and the default value is no.

computation_method

  • Optional: Conditional

  • Type: String

  • Description: Possible options include vt and fem. This parameter is required if include_topography is set to yes.

maximum_octant_level

  • Optional: Conditional

  • Type: Integer

  • Description: The maximum octant level allowed. It can be a integer between 1 and 30. As mentioned in Time and Frequency, the minimum element size is calculated as \(h_{min} = \frac{V_{S, min}}{N_p f_{max}}\). A proper value for maximum_octant_level should satisfy the condition \(\frac{\text{(The largest dimension of the domain)}}{2^n} < h_{min}\). This parameter is required if include_topography is set to yes.

topographybase_zcoord

  • Optional: Conditional

  • Type: Float

  • Description: The base z coordinate of the topography. It should be a floating number bigger than 0 that satisfy the condition \(z_b = \frac{\text{(The largest dimension of the domain)}}{2^n} > e_h\), where \(z_b\) is topographybase_zcoord, \(e_h\) is the highest elevation in the domain, and n is an integer that satisfies the condition. This parameter is required if include_topography is set to yes.

type_of_etree

  • Optional: Conditional

  • Type: String

  • Description: Possible options include sqd and full. This parameter is required if include_topography is set to yes.

topography_directory

  • Optional: Yes

  • Type: Path

  • Description: The path to the directory where the topography information is stored. This is an optional parameter and the default value is inputfiles/topography.

consider_nonlinear_topography

  • Optional: Yes

  • Type: Yes or No

  • Description: Whether to consider topography in a nonlinear analysis. This is an optional parameter and the default value is no.
