CFD 计算对计算网格有特殊的要求
CFD 计算对计算网格有特殊的要求，一是考虑到近壁粘性效应采用较密的贴体网格，二是网格的疏密程度与流场参数的变化梯度大体一致。
对于面网格，可以设置平行于给定边的边界层网格，可以指定第二层与第一层的间距比，及总的层数。
对于体网格，也可以设置垂直于壁面方向的边界层，从而可以划分出高质量的贴体网格。
而其它通用的CAE 前处理器主要是根据结构强度分析的需要而设计的，在结构分析中不存在边界层问题，因而采用这种工具生成的网格难以满足CFD 计算要求，而Gambit 软件解决了这个特殊要求。
如果先在一条边上画密网格再在之上画边界层，边界层与网格能很好的对应起来如果直接在一条边上画边界层，则边界层横向之间的距离很宽怎么设置边界层横向之间的距离，即不用先画网格也能画出横向距离很密的边界层来？在划分边界层网格之前，用粘性网格间距计算器，计算出想要的y+值对应的第一层网格高度；第一层高度出来之后，关于网格的纵横向网格间距之比，也就是边界层第一层网格高度与横向间距之比，大概在1/sqrt(Re)，最为适宜；先在你要划边界层网格的边上划分线网格，然后再划分边界层。
gambit本人也用了一段时间，六面体网格四面体网格我都画过，但是最头疼的还是三维边界层网格的生成。
用gambit自带的边界层网格生成功能画出来的边界层网格经常达不到好的效果，或者对于复杂的外形根本就无法生成边界层网格。
为此我就采用手动设置边界层，但是比较费时间，效果还一般。
不知道大家是不是也遇到相似的问题，或者有更好的方法，请指点一下，先谢谢了！22 什么叫松弛因子？松弛因子对计算结果有什么样的影响？它对计算的收敛情况又有什么样的影响？1、亚松驰（Under Relaxation）：所谓亚松驰就是将本层次计算结果与上一层次结果的差值作适当缩减，以避免由于差值过大而引起非线性迭代过程的发散。
用通用变量来写出时，为松驰因子（Relaxati on Factors）。

手工制作全过程作文英语
Crafting is an art that requires patience, creativity, and a keen eye for detail. Heres a stepbystep account of the process of creating a handmade item, written in American English.Title: The Art of Handmade CreationStep 1: Inspiration and ConceptualizationThe journey begins with a spark of inspiration. It could be anything from a nature walk to a piece of art. I decided to make a personalized photo frame after seeing a beautiful sunset. The concept was to capture the essence of the moment in a frame that would stand out.Step 2: Gathering MaterialsOnce the idea is clear, the next step is to gather all the necessary materials. For my photo frame, I needed a wooden frame, paint, brushes, varnish, and of course, the photograph. I headed to the local craft store to pick up the supplies.Step 3: Preparing the BaseThe wooden frame needed some preparation before I could start painting. I sanded it down to ensure a smooth surface and then wiped it clean to remove any dust.Step 4: Sketching the DesignBefore applying the paint, I sketched the design lightly onto the frame using a pencil. I wanted to incorporate elements of the sunset, so I drew soft curves and lines to mimic the sky.Step 5: PaintingWith the design in place, I started painting. I used acrylic paints for their vibrant colors and quickdrying properties. I carefully painted the sky and the sun, layering the colors to create depth.Step 6: Adding DetailsAfter the base colors dried, I added finer details. I painted small clouds and used a sponge to dab on texture for the suns rays.Step 7: VarnishingOnce the paint was completely dry, I applied a coat of varnish to protect the paint and give it a glossy finish.Step 8: Assembling the FrameWith the painting done, I carefully inserted the photograph into the frame, ensuring it was centered and secure.Step 9: Quality CheckBefore considering the project complete, I did a final quality check. I looked for any smudges or imperfections and made sure the photograph was wellprotected.Step 10: Displaying the CreationThe final step was to find the perfect spot to display my handmade photo frame. I placed it on my living room shelf, where it catches the morning light and brings a touch of warmth to the room.Creating something by hand is not just about the end product its about the process, the learning, and the satisfaction of seeing an idea come to life. Each handmade item tells a story, and this photo frame is a testament to a beautiful sunset and the joy of crafting.。
