IBAMR 0.7.1

IBAMR 0.7.1 was released on July 2, 2020 and fixes a small number of bugs in IBAMR 0.7.0, including:

IBAMR 0.7.1 is available on the GitHub release page.

IBAMR 0.7.0 was released on June 17, 2020. Major improvements include:

A completely rewritten implementation of force spreading for IBFE which is several times faster than the older version.
The way which Lagrangian elements were associated with patches has been upgraded so that only elements within one cell of a patch are associated with the patch (instead of using a width based on the IB stencil). This lowers the total number of libMesh objects associated with each patch by about 25%.
The sweeping algorithm for 3D level set computations has been rewritten and now requires about 30% fewer iterations.
A new example that demonstrates how ghost cell filling works in IBAMR.

IBAMR 0.7.0 is available on the GitHub release page.

IBAMR 0.6.0 was released on December 24, 2019. Major improvements include:

A new set of classes for solving complex fluid equations, including Giesekus relaxation and Oldroyd-B.
Several new classes for handling wave generation.
A new partitioning algorithm for partitioning the IB points separately from the data for IBFEMethod.

IBAMR 0.6.0 is available on the GitHub release page.

IBAMR 0.5.0 was released on July 27, 2019. Major improvements include:

An overhauled test suite utilizing on our own test runner attest. About 100 new tests have been added.
Seven new multiphase flow examples.
Two classes implementing Brinkman penalization algorithms.

IBAMR 0.5.0 is available on the GitHub release page.

IBAMR 0.4.1 was released on April 17, 2019. This is a minor update to the 0.4 branch which fixes compatibility with an older version of libMesh.

IBAMR 0.4.1 is available on the GitHub release page.

IBAMR 0.4.0 was released on March 29, 2019. This is the first version of IBAMR to require C++11. Major improvements include:

Improved performance in the IBFE subsystem: some codes were shown to run 3x faster.
Experimental support for partitioning data based on the number of interaction points.
Several code cleanups that made use of C++11.

See doc/news/changes/0.3.0-vs-0.4.0.html for a complete list of changes.

IBAMR 0.4.0 is available on the GitHub release page.

IBAMR 0.3.0 was released on September 22, 2018. Major improvements include:

a new example (IBFE/explicit/ex9/) showing how to tether codimension one and codimension zero bodies together
a new example (multiphase_flow/ex3) demonstrating convection of a high density droplet
a new example (ConstraintIB/moving_plate) demonstrating a moving control volume
A new class IBFEInstrumentPanel which measures velocity and pressure
Compatibility with libMesh 1.0 and newer
Compatibility with muParser 2.2.3 and newer

IBAMR 0.3.0 is available on the GitHub release page.
