To use these individually start your file with: from pipemesh import pieces, gmsh model = gmsh. This makes the information a little easier to access than using just the GMSH API.

The classes store information of the object, such as the centre and direction of its faces, as well as functions to update the information when transformations are applied to them. pieces.pyĬontains classes (and some useful functions for said classes) which represent cylindrical GMSH objects.

For full information on what settings can be changed, visit the documentation. write_mpml ( 'generated_mpml' )Īs the options can be set in python, this means that multiple simulations can be set up, with for example, varying reynolds numbers or varying input surfaces. set_all ( sim_name = 'junction_flow_test_case', msh_file = 'src/pipe', dump_ids = entry_phys_ids, density = 1000, inlet_phys_ids = inlets, inlet_velocities = inlet_velocities, outlet_phys_ids = outlets, cyl_phys_ids = cyl_phys_ids, max_no_nodes = 10000, min_mesh_size = 0.2, finish_time = 1.0, t_adapt_delay = 0.5 ) # Write mpml file - extension not needed. AutoMPML () # Change various options (the defaults are fairly sensible) options. get_velocities_vel_mag ( inlets, vel, 1000, 1e-3 ) # Create options object options = auto_mpml. get_cyl_phys_ids () # Select the inlet and the first outlet as inlets inlets = entry_phys_ids # Select the remainding inlet/outlets as outlets outlets = entry_phys_ids # Get velocity vectors for velocity magnitude 0.02 vel = 0.02 inlet_velocities = network.

Options that can be changed are relevant to conducting a pipe flow investigation with IC-FERST.Įxample: from pipemesh import pipes from pipemesh.icferst import auto_mpml # Generate a network network = pipes. This isn't actually automatic, but can save time by not editing mpml files with Diamond. mpml file used with IC-FERST by inputting the user values in the right places. The file auto_mpml.py contains the class AutoMPML. Network has get_phys_ids methods, which can be used with AutoMPML. Which will write the file 'example.msh', as a msh2 binary file. generate ( filename = 'example', binary = False, write_info = False, mesh_format = 'msh2', write_xml = False run_gui = False ) Information can be obtained and written to file. Once the Network is complete, you can fuse the objects together and create physical surfaces and volumes, and set the local mesh sizes. add_cylinder ( 1, 0.1, out_number = 2 ) network. For more information on each function, please visit the documentation linked above. Where out_number specifies which outlet of the pipe the piece will be added to. add_cylinder ( 1, 0.1, out_number = 1 ) network. Then added to using one of the following commands: network. A script is started by creating the Network object: from pipemesh import pipes network = pipes. Once installed, scripts to generate pipe and pipe network meshes can be created. If you really don't want to use pip to install, clone the repository, and add acse-9./pipemesh/ to PATH so python can find it. Ensure to use the virtual environment every time you need to use pipemesh. Then simply place the libgmsh files into virtual_env/lib/site-packages/pipemesh/. $mkdir virtual_env # Name of your virtual environment $python3 -m venv virtual_env

Change mesh size gui gmsh install#

# If you don't have venv $sudo apt-get install python3-venv Place the files libgmsh.so, libgmsh.so.4.3 and libgmsh.so.4.3.0 in this folder.Ī virtual environment can be useful to locate the site-packages directory more easily. Once completed, navigate to site-packages/pipemesh of the python installation used. Installation $python3 -m pip install -user pipemesh

Pipemesh is currently only supported on Linux systems (e.g. SciPy (and NumPy, installed with SciPy).

Download the SDK and navigate to the lib/ folder to find these, or use the versions hosted in this repository.

libgmsh.so, libgmsh.so.4.3, libgmsh.so.4.3.0 (or higher) from the GMSH SDK.

The documentation for pipemesh can be found here. These tools use the GMSH-SDK (or GMSH-API), available here.
