• Hide Ansys Fluent Logo : Display > Options > Layout > Deselect Logo

• Change Ansys Fluent background color to white, white background

- In the command line:

           >>   /display/set/colors/color-scheme

           >>  classic (change from default workbench to classic)

           >>  /display/set/colors/foreground/

           >> "black"

           >> /display/set/colors/background

           >> "white"

           >> /display/re-render

Enable laminar models, and activate the vorticity magnitude
>> Define/Models/Viscous >  Laminar

• Check Mesh information, Cells, Faces, Nodes

>> Mesh > Info > Size

• Run Fluent from the specified time step (not from first time step): applicable for the case was terminated before and now you want to continue restart it from the last save.

rc    case.cas     : Read case file
rd
/solve/dual-time-iterate/  Number of physical time steps [1]         /* syntax */
s/d                                                                                                  /*  short form */

dual-time-iterate: Perform unsteady iterations for a specified number of time steps.
Number of physical time steps: desired ending time steps

E.g., run from 1000, and stop at 2000
rc case_1000.cas
rd case_1000.dat
solve/dual-time-iterate 2000

Problem: Even it is calculated from the n th time step but it may be save in form of cas_01.cas, cas_02.cas  with auto-save. You can overcome it by using manual command: wc, wd

Sketchup: Design, Architecture

Introducing SketchUp 2013

For SketchUp 2013, we focused on two things: making LayOut even more powerful, and building an ecosystem that makes it easier for millions of SketchUp modelers to find and use the plugins, add-ons and extensions they need. Upgrade a Pro license now.

Introducing Extension Warehouse

What if adding new extensions to SketchUp was as easy as installing an app on your smartphone? In 2013, we’ve made it dead simple to turn SketchUp into exactly what you need it to be. Need a special tool? There’s an excellent chance someone’s already built it. Now you can research, download and install extensions without ever having to leave SketchUp. Every useful extension in one place—that’s the all-new Extension Warehouse.

Pattern Fills

Drawing a sectional view? Now you can fill shapes in LayOut with hatching and other patterns. Choose from a large library of standards—construction materials, geometric tiles, dot screens—or create your own favorites. Patterns can be rotated, scaled or used as-is. You can even combine Pattern Fills with solid colors to create an endless number of variations.

Copy Array

You know how SketchUp lets you easily create multiple copies of an object with your keyboard? Those are called arrays, and now LayOut lets you make them, too. Move a copy, type how many copies you want, type the letter ‘x’ and Enter. Presto! Presto! Presto! Presto! Presto! Copying is fun.

Speedier Vector Rendering

When you need to print a drawing really big, sometimes it’s helpful to vector-render your SketchUp model views. Doing so makes lines look smooth and reduces wait times for all but the most complex models. In the latest version of LayOut, vector rendering is faster than it’s ever been.

Faster Screen Redraw

Every time you zoom, pan or move an entity on the page, LayOut has to re-draw the picture you see on your screen. For this version, we massaged the code so there’s a noticeable improvement in the speed at which this happens. LayOut should feel snappier, especially as your document gets more complex.

Numbered Pages in the Pages panel

Another small but incredibly useful tweak: LayOut’s Pages panel now displays page numbers, which makes it easier to print and export portions of your document.

Curved Label Leader Lines

Creating a jauntily curved callout line for a label used to be a five-step, two-handed operation:
Click. Click. Tool switch. Double-click. Click-drag-with-a-modifier-key.
In the latest version of LayOut, curving a label line goes like this:
Click-drag.
Isn’t progress something?

Dashes in Dimensions

Ask the guy with the 86 foot ceiling if readable dimensions are important. It’s a little thing, but we added dashes to LayOut’s dimension labels to make them easier to read.

Smarter Toolbars in Windows

It used to be that the toolbars for all of your delicious plugins would move around your screen between SketchUp sessions. We heard that drove you crazy, so we re-engineered our Windows UI to make things a whole lot better. In 2013, you can even drag native tool icons between toolbars. Make SketchUp look the way you want it to.

Video Export

Exporting high-quality animations from SketchUp 2013 is easier than ever. Using the default settings yields HD videos at 720p, encoded in any of the three most popular, modern formats: H.264, AVI and WebM. Picture quality is much better, and file sizes are smaller as well.

Zoom In More

We increased LayOut’s maximum zoom capability by a factor of ten, from 1000% to 10,000%. At that magnification level, your sofa would be the size of Jupiter. Or thereabouts.

enGrid - open-source mesh generation

enGrid is an open-source mesh generation software with CFD applications in mind. enGrid uses an in-house development for surface meshing and prismatic boundary layers; a module for hex far-fields will be added in the next release. Tetrahedral parts of the mesh are created by calling the Netgen library. Internally, enGrid uses the VTK data structures as well as the *.vtu file format.
Currently enGrid has interfaces to Blender [3], Gmsh, STL, and a few other file formats. Gmsh can be used to import STEP and IGES files and it can also be used for simple geometry modeling.
Since the 1.2 release, enGrid provides native export to OpenFOAM® and since 1.4 for SU2. This includes export capabilities for complete OpenFOAM cases (including boundary conditions), as well as support for polyhedral cells. enGrid is released under the GPL and we hope that it is a useful addition to the open-source CFD community.

Computational Fluid-Structure Interaction A Short Course in Barcelona, July 19-20, 2014

Computational Fluid-Structure Interaction

A Short Course in Barcelona

July 19-20, 2014

http://www.tafsm.org/BarcFSI2014/

The short course is on Saturday and Sunday before the World Congress on Computational Mechanics, July 21-25, 2014, Barcelona. One can register just for the short course or take advantage of special (conference + short course) registrations. There is also a special registration for full-time students.

Instructors: Y. Bazilevs (UCSD), K. Takizawa (Waseda), and T. Tezduyar (Rice)

Short-Course Overview

The lectures will focus on the fundamental concepts and advanced topics in computational fluid-structure interaction (FSI). The fundamental concepts will include the stabilized formulations, ALE method and ALE-VMS technique, space-time (ST) method and ST-VMS technique, mesh update methods for flows with moving interfaces, iterative solution techniques and parallel computing concepts, and isogeometric analysis. The advanced topics are the ST computational FSI techniques, ALE-VMS computational FSI techniques, and FSI coupling techniques. The topics to be covered include the core technologies and the special techniques targeting specific classes of problems, such as cardiovascular FSI, parachute FSI, and wind-turbine modeling.

Registration Deadline: July 1, 2014
