There is a new example of eigenvalues of a circular membrane. View the example here. To run the example at the MATLAB® command line:
The meshing (geometry triangulation) functions in initmesh and adaptmesh provide an enhancement option for increased meshing speed and robustness. Choose the enhanced algorithm by setting the MesherVersion name-value pair to 'R2013a'. The default MesherVersion value of 'preR2013a' gives the same mesh as previous toolbox versions.
The enhancement is available in pdetool in the Mesh > Parameters > Mesher version menu.
There is a new example of heat distribution in a radioactive rod. View the example here. To run the example at the MATLAB command line:
pdegplot now optionally labels:
The edges in the geometry
The subdomains in the geometry
To obtain these labels, set the edgeLabels or subdomainLabels name-value pairs to 'on'. For details, see the pdegplot reference page.
There is a new example of uniform pressure load on a thin plate. View the example here. To run the example at the MATLAB command line:
There is a new example of nonlinear heat transfer in a thin plate. View the example here. To run the example at the MATLAB command line:
There is a new example of a system of coupled PDEs. View the example here. To run the example at the MATLAB command line:
The pdesmech function now calculates shear strain according to the engineering shear strain definition. This has always been the documented behavior. However, the previous calculation was performed according to the tensor shear strain calculation, which gives half the value of the engineering shear strain.
pdesmech now returns shear strain values exactly twice as large as before.
