<hr />
<div>At the origin of the PALM project, if we go as back as 1996, we find the operational ocean forecasting project MERCATOR.<br />
The head of the MERCATOR project of the time, Philippe Courtier, suggested that a data assimilation suite could be designed and implemented as a coupling. The different tasks - running a forecast, apply the observation operator, computing the misfit, approximate the error statistics, invert matrices, minimize a cost function and so on - were to be thought of as independent pieces of code to be assembled within a portable, flexible and efficient framework. Since most of the data assimilation algorithms can be implemented as a different sequence of the same functional units (cf. Lagarde, Piacentini, Thual, A new representation of data assimilation methods: the PALM flow charting approach, Q.J.R.M.S., 127 (2001), 189-207), this approach was the most suitable for a research and development context, where many methods were to be implemented and compared.<br />
<br />
<br />
<br />
The PALM Team at CERFACS was in charge of the development of the software backbone of the project. It was a technological challenge: to develop a dynamic parallel coupler and its user interface that had to be used on a variety of platforms under the efficiency constraints of operational applications.<br />
Such a challenging task was carried on in two steps: <br />
<br />
- first a fully featured prototype was implemented using the available technology at the end of the 90's. At the issue of this phase an MPI1 based version of the coupler was released with the name PALM_RESEARCH afterwards changed to PALM_SP.<br />
<br />
- based on the expertise developed on the prototype, the final MPI2 based version of PALM was designed and implemented. It was released with the name PALM MP.<br />
<br />
<br />
<br />
Thanks to the flexibility of the approach, the non-specific formalism used to describe the coupling interfaces and the portability of the software, PALM established itself as a natural choice for all sorts of dynamic parallel coupling and code assembling projects.<br />
In particular, PALM has been adopted for a number of multiphysics simulations in computational fluid dynamics. To answer the requirements of the future multiphysics high performance simulations, PALM has integrated the CWIPI communication and interpolation library developed by ONERA.<br />
To make this and any future collaboration easier, PALM is currently distributed as an open source application under the LGPL v3 license, with the name OpenPALM.<br />

<div>Fluid-structure interaction (FSI) simulations are coupled CFD (fluids) and [[FEM]] (mechanics) cases. FSI is a part of [[mulitphysics simulations]] and an actual main focus in CFD development. As these solvers use different methods and codes, the transfer of the boundary conditions at the interface is an important feature of an FSI solution. <br />
<br />
== Coupling ==<br />
=== 1-way FSI ===<br />
1-way FSI typically describes the pure mapping of physical properties resulting from the analysis of a CFD-/FE-model to another FE-model. The two models typically do not rely on matching meshes (e.g. mapping aerodynamic pressure distribution onto a structural Finite Element model). However in the case of 1-way FSI the mapping of the physical properties does not include the modification of any of the meshes. <br />
<br />
=== 2-way FSI ===<br />
In the case of 2-way FSI the mapping is done in an iterative loop i.e. the results of the first model are mapped to the second model and these results are mapped back to the first model and so on until convergence is found or the process is stopped manually. Very often in the case of 2-way FSI one of the mapping steps involves the modification/morphing of the mesh of one or both of the models (e.g. mapping deformations coming from aerodynamic loads back to the CFD-model and re-evaluating the CFD-model in the deformed configuration).<br />
<br />
== Mesh Morphing ==<br />
In most cases FSI is quite simple to realize even employing meshes not matching. However as soon as mesh-morphing is needed the whole process gets much more difficult and only few software solutions are around that can handle this. They key-problems with mesh-morphing are:<br />
<br />
* Performance: Typical CFD-models as employed today in Formula 1 or Aerospace require very efficient morphing algorithms. A lot of the straight-forward approaches are not able to handle CFD-models consisting of several millions of cells.<br />
* Surface Quality: For calculating pressure distributions in aerodynamics the surface quality in terms of continuity has to be quite high. Otherwise one starts to observe oscillations in the pressure fields. This is namely a challenge in the case where the mesh providing the deformation (typically the structural FE-mesh) is significantly coarser then the surface mesh of the CFD-model (which is quite common).<br />

<div>At the origin of the PALM project, if we go as back as 1996, we find the operational ocean forecasting project MERCATOR.<br />
The head of the MERCATOR project of the time, Philippe Courtier, suggested that a data assimilation suite could be designed and implemented as a coupling. The different tasks - running a forecast, apply the observation operator, computing the misfit, approximate the error statistics, invert matrices, minimize a cost function and so on - were to be thought of as independent pieces of code to be assembled within a portable, flexible and efficient framework. Since most of the data assimilation algorithms can be implemented as a different sequence of the same functional units (cf. Lagarde, Piacentini, Thual, A new representation of data assimilation methods: the PALM flow charting approach, Q.J.R.M.S., 127 (2001), 189-207), this approach was the most suitable for a research and development context, where many methods were to be implemented and compared.<br />
<br />
<br />
<br />
The PALM Team at CERFACS was in charge of the development of the software backbone of the project. It was a technological challenge: to develop a dynamic parallel coupler and its user interface that had to be used on a variety of platforms under the efficiency constraints of operational applications.<br />
Such a challenging task was carried on in two steps: <br />
<br />
- first a fully featured prototype was implemented using the available technology at the end of the 90's. At the issue of this phase an MPI1 based version of the coupler was released with the name PALM_RESEARCH afterwards changed to PALM_SP.<br />
<br />
- based on the expertise developed on the prototype, the final MPI2 based version of PALM was designed and implemented. It was released with the name PALM MP.<br />
<br />
<br />
<br />
Thanks to the flexibility of the approach, the non-specific formalism used to describe the coupling interfaces and the portability of the software, PALM established itself as a natural choice for all sorts of dynamic parallel coupling and code assembling projects.<br />
In particular, PALM has been adopted for a number of multiphysics simulations in computational fluid dynamics. To answer the requirements of the future multiphysics high performance simulations, PALM has integrated the CWIPI communication and interpolation library developed by ONERA.<br />
To make this and any future collaboration easier, PALM is currently distributed as an open source application under the LGPL v3 license, with the name O-PALM.<br />

To make this and any future collaboration easier, PALM is currently distributed as an open source application under the LGPL v3 license, with the name O-PALM.</div>Florenthttps://www.cfd-online.com/Wiki/CodesCodes2011-02-03T08:19:03Z<p>Florent: Add O-PALM</p>
