Summary Also known as Model type Model part of larger framework Note on status model Date note status model Technical specs Supported platforms Unix, Linux Other platform Programming language Python Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2010 Does model development still take place? Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code, As teaching tool Source code availability (Or provide future intension) Through owner"Through owner" is not in the list (Through web repository, Through CSDMS repository) of allowed values for the "Source code availability" property., Through CSDMS repository Source web address Source csdms web address Program license type GPL v3 Program license type other Memory requirements Typical run time Minutes to populate cofactor matrix, ~1 second for solution In/Output Describe input parameters Elastic thickness map (ASCII) Load map (ASCII) dx, dy Material properties Young's modulus Poisson's ratio density of load density of infilling material (optional; this can also be done via iteration for more complicated situations Only the elastic thickness and load need to be actual input files. The rest (scalars) can be specified at the command line interface. Input format ASCII Other input format Describe output parameters Cofactor matrix (*.mtx sparse matrix file; ASCII) Flexural response map (ASCII) Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Process Describe processes represented by the model Response of a lithospheric plate, potentially with nonuniform elastic thickness, to an applied surface load Describe key physical parameters and equations [[Describe key physical parameters::We solve the PDE for lithospheric flexure in 2 dimensions: <math> \nabla^2\left(D(x,y)\nabla^2 w \right) + \Delta \rho g w = q(x,y) </math> Here, $D$ is the flexural rigidity, $w$ is the vertical displacement at each $(x,y)$, $\Delta \rho$ is the mantle density minus the density of infilling material, $g$ is gravitational acceleration, and $q$ is the applied load. We follow Wees and Cloetingh (1994) in acknowledging that flexural rigidity is a tensor property: <math> D = \frac{E T_e^3}{12\left(1-\nu^2\right)} \left[ \begin{array}{ccc} 1 & \nu & 0 \\ \nu & 1 & 0 \\ 0 & 0 & \frac{1-\nu}{2} \end{array} \right] </math>]] Describe length scale and resolution constraints Insufficiently tested to know. Describe time scale and resolution constraints Currently does not time-evolve. I would like to couple this to a 3D viscoelastic mantle at some point, but this hasn't happened yet. Describe any numerical limitations and issues Insufficiently tested to know. Testing Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Other Do you have current or future plans for collaborating with other researchers? Is there a manual available?
