V Kratos Workshop in TUM

cabecera-kratos

The fifth edition of the Kratos Multiphysics Workshop will take place at the Technical University of Munich (TUM) from the 25th to the 27th of March 2019.  The Kratos Workshop is the main meeting of users and developers of the Kratos Multiphysics open-source framework. Its goal is to bring together developers, industrial users and researchers to present new features in the code and discuss new and potential applications.

During three days several presentations and discussion roundables will take place. As well as a hands-on Kratos Course. Participants are asked to bring their own laptop. The course will assume a basic level of knowledge of the Python language.

Significant advances in FIBRESHIP project

The European project FIBRESHIP,  an innovation project funded by the EU’s Horizon 2020 programme, has achieved significants advances during the first 18 months.

The main objective of the FIBRESHIP project is to generate the regulatory framework for designing and building of large-length ships in FRP (Fibre-Reinforced Polymers) material overcoming the technical challenges identified. In order to achieve this goal, the project is qualifying and auditing innovative FRP materials for marine applications, elaborating new designs and production guidelines, generating production and inspection methodologies, and developing numerical software tools capable of assessing the structural performance validated through experimental testing.

CIMNE and COMPASSIS are part of the project consortium and participates in different phases of the project.

CIMNE has developed an innovative computational model capable of simulating the non-linear performance of composite materials based on the Serial/Parallel Mixing Theory (S/P RoM). This method is able to predict different failure modes, such as delamination, matrix cracking or fibre breakage.

The numerical model has been validated using the results from a set of mechanical tests carried out at the University of Limerick (ULIM). Once the validation phase was successfully completed, the numerical model has been implemented by COMPASSIS in the commercial CAE software RamSeries v15, a GiD inside product.

Check all the achieved advances in the CORDIS website.

New GiD official version 14.0.2

The new GiD14.0.2 official version have been released and its ready to download.

Check what’s new in this version:

General:

  • Graphical fonts¬†can be drawnwith even smoother edges using lcd subpixel rendering on preferences –> fonts panel.

Preprocess:

  • Fixed bug that made GiD crash in some pathological situations with semi-structured volumes and skip entities automatically option set.

Check¬†what’s new¬†in this version:

General: 

  • Background image and textures:¬†now a GIF image can be used.
  • Progress bar¬†tcl error solved.
  • Snapshots:¬†red line when doing gif solved. Also happened with gif and jpg snapshots.
  • Node limit increased to 10.000 nodes for free version.
  • Graphical fonts¬†can be drawnwith even smoother edges using lcd subpixel rendering on preferences –> fonts panel.
  • Preferences:¬†now preferences are stored inside¬†$HOME/.gid/ folder, these include GiD’s, mesher and problem-type preferences.

Preprocess:

  • Frozen layers:¬†avoid delete lowerentities on frozen layers.
  • Mesh menu options¬†correctly placed: Create raster nodes and elements.
  • New import option, to import gidml mesh format (input/output format for GiD Mesh Library).
  • Overlapped labels¬†in preprocess are¬†drawn in RED.¬†Option to enable or disable this feature in the 3rd mouse button menu, under Label. This will help to indenfity geometrical entities which are potentially too close, for instance repeated points, which will be affected by a¬†Geometry –> Collapse¬†operation. Overlapped labels are the ones which share almost the same space coordinates, i.e. within the Automatic (import) tolerance, defined in the¬†Import¬†section of the preferences window.
  • Divide surface tool allow change view with U or V selection window is opened (window changed from modal to modeless), and¬†u == 0, v == 0¬†lines drawn enhanced
  • Fixed bug that made GiD crash in some pathological situations with semi-structured volumes and skip entities automatically option set.
  • Fixed bug affecting some models when checking the compatibilities between meshing properties before beginning the meshing process.
  • Planar surfaces store esplicitly the render mesh (previously only a OpenGL drawing list was known), and it is saved in the¬†.rdr¬†render mesh file.

Postprocess:

  • Graphs window: new clipboard copy option in contextual menu (e.g. to allow paste in MS. Excel)
  • Multiple Windows:¬†options moved as sub-menu in the top menu bar, as in preprocess.
  • Results’ cache + Convert cuts to sets:¬†add warning and suggestion to increase memory and save model just after the conversions, otherwise the created results will be lost.
  • Complex results:¬†solved crash when drawing complex matrices after drawing complex vectors.

  • Graphs labels¬†as in postprocess view.
  • Option to enable¬†multiple line labels,¬†for graphs, vectors and matrix labels.

  • Line graphs:
    • correct calculation of the ‘line variation‘ option, i.e. solved loop problem. Line variation uses the 3D distance of the created graph as abcisses, for instance on non planar surfaces.
    • added option ‘Line projection‘, which uses the 2-clicked-point-line projected distances as abcisses.
    • added ‘2d constraint’ option to the contextual menu of line graphs, so line graphs are created by projecting the created line along the z axis to the surface and discarding the ‘z-coord’ of the surface (for the line variation and line projection options).
  • Polar graphs:¬†now labels in polar graphs are shown where they should be. Selection of polar labels also works now.

  • Complex scalars:¬†also appear in vectors menu, to display the complex number as a vector, as well as¬†Complex vectors¬†components (x, y, z), which can be viewed as separated complex numbers.
  • Animation of complex vectors: An harmonic animation can be performed for a complex vector when this is used to deform the mesh and the ‘single step animation’ is selected in the Animation Window. After confirming the harmonic animation, the number of steps for this animation will be asked, the deformation factor and the user will be informed that temporary results will be created to perform the animation. When the harmonic animation is stopped or the animation window is closed these temporary results will be deleted and the visualization will go back to the first deformation.
  • Interior faces of volume sets:¬†now enabling interior faces of hexahedra, prisms and pyramids they are drawn in va/vbo when visualizing gauss points results (contour fill).
  • Create results window:¬†allow operate with results ‘on gauss points’ with more than 1 gauss point, and efficiency enhanced using objarray objects.
  • Main Matrix results:¬†corrected crash when reading these result types.
  • Deformation on results’ icon bar:¬†now the ‘1x’ button instead of deformation the mesh with factor 1x, asks the user for a new factor. also the scale is adjusted so that for very huge factors (1e+20) factor 1 appears as 1 and not as 0 (due to accuracy error).
