Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Modular Model part of larger framework Note on status model Date note status model Keywords: turbidity current, numerical simulation, complex topography, polydisperse suspension, sedimentation, parallel computing, Name Mohamad Nasr-Azadani Type of contact Model developer Institute / Organization UC Santa Barbara Postal address 1 Engr II Bldg, Room 2301 Postal address 2 UC Santa Barbara Town / City Santa Barbara Postal code 93106 State California Country United States Email address mmnasr@gmail.com Phone (805) 893-6107 Fax (805) 893-8651 Supported platforms Linux, Mac OS, Windows Other platform Programming language C Other program language Code optimized Single Processor, Multiple Processors Multiple processors implemented Distributed memory Nr of distributed processors Nr of shared processors Start year development 2007 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 Source code availability (Or provide future intension) Through CSDMS repository Source web address Source csdms web address Program license type GPL v2 Program license type other Memory requirements Roughly, 1 GB per 270,000 grid cells. Typical run time Day(s) Describe input parameters A self-explanatory file "input.inp" should be set before running the code. Flow and particle parameters such as Reynolds number, Peclet number, particle settling velocity(ies) can be set here. Also, number of grid nodes, domain length, output file flags and simulation runtime, etc should be entered. Input format ASCII Other input format Describe output parameters Depending on the flags set in the "input.inp" file, flow properties such as velocity, pressure, particle concentration(s), particle deposit mass, bottom shear stress, kinetic and potential energy, dissipation rate, suspended particle mass, current front location, and etc are recorded at the given timesteps. Output format ASCII, Binary Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? Yes Describe post-processing software A simple C++ code is called to convert raw binary data to "*.vtr" (see VTK format) that can be read by a software called Paraview. Visualization software needed? Yes If above answer is yes Matlab Other visualization software Paraview Describe processes represented by the model Any density driven current including particle-laden flows produced by the lock-exchange (or continuous inflow) can be simulated. The flow can interact with any arbitrary topography on the bottom. Describe key physical parameters and equations Navier-Stokes equation in Bousinessq approximations: to describe the ambient fluid's motion Transport equation(s): to describe the particle and/or salinity concentration field evolution. Reynolds number, Peclet number, particle settling velocities. Describe length scale and resolution constraints The current version is a DNS code, i.e. no turbulence model is incorporated yet. Hence, grid resolution should be carefully treated to resolve all the flow scales. In other words, limited by the computational costs, we are restricted to low Reynolds numbers (O(1,000)-O(10,000)). Describe time scale and resolution constraints Describe any numerical limitations and issues 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 Do you have current or future plans for collaborating with other researchers? Is there a manual available? No Upload manual if available: Model website if any Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No not possible BMI compliant No not possible WMT component Not yet"Not yet" is not in the list (Yes, In progress, No but possible, No not possible) of allowed values for the "Code CMT compliant or not" property. PyMT component Is this a data component Can be coupled with:
