打扰大家，发一条博士和博后的招聘信息：
以下是小木虫的链接：
CFD-Online链接：
我们组要是做心血管的血流模拟，做实验做计算都需要。
实验室在Worcester， MA，离波士顿开车一小时。
现处于初创阶段，目标招到4位博后+5位博士。希望您的加入！
有点啰嗦，不好意思。感谢大家的时间！
@eason 如果是multi-body 问题，然后其中一个body需要IBM，就直接用Gmsh做其他body 的conforming mesh就可以。只有一个body且需要IBM，就可以做一个enclosed的正方体或者圆柱体，画网格就行。

@五好青年
不是很熟悉OpenFoam的IB方法。
没有使用过OpenFoam里的IBM。我们平时做IBM，用Gmsh做IB Points.
圆柱附近的网格，是否要比不用浸入边界法（实际建模）模拟时，网格要多很多呢？
不一定。但是IB方法当中，边界稳定性可能会比非IB的差一点，更密的网格可以帮助解决这个问题。
用浸入边界做圆柱绕流，结果后处理速度云图，为啥圆柱位置也有蓝色云图呢？
这很正常，IB方法就是用圆柱内的速度去补偿圆柱外的，从而在圆柱表面得到需要的速度（比如no-slip）。所以IB方法里，圆柱内是会有速度的，都是artificial velocity。
加油！
@李东岳 Thanks! Dongyue! It was a headache for enrolling students and teaching under pandemic. Anyhow, the semester is almost done. The Stipend is 35326 USD and the Tuition is 8000 USD.
Also, I followed quite closely with your WeChat group. Are you going to show us the best Workstation specs for CFD? :)
Thanks and I am very grateful to be in this community!
@Jacob-Z 在 请问有哪些类似于ICEM、pointwiae的开源网格软件？ 中说：
Netgen
应该可以，你可以试一下。我一般是Netgen做完之后，去Gmsh里修整以下，然后再导出msh文件。
Ph.D. position in image-based FSI and machine learning
A new Ph.D. position (fall 2020 and spring/fall 2021) is available in the department of biomedical engineering at UMass Lowell, for research and development of (medical) image-based fluid-structure interaction modeling with machine learning to advance the frontiers of personalized medicine (involving surgery, intervention, and medical devices). the pi's current research thrusts can be found in the following links: researchgate or googlescholar.
Qualifications:
• a bachelor or equivalent degree in engineering (mechanical, biomedical, and aerospace), applied mathematics, or related fields. applicants with a master’s degree are preferred.
• solid understanding of numerical methods, fluid dynamics, and solid mechanics. applicants with previous experience in biomechanics (biofluid and/or biosolid mechanics) are preferred.
• excellent programming and analytical skills.
The graduate research assistantship includes a monthly stipend and tuition.
Interested students should send the following items to zhenglunalan_wei@uml.edu with a“Ph.D. Application” in the subject line.
• curriculum vitae
• personal statement (including, research interests)
• contact information for three references
IB Method的优势就是背景网格不用变动，可以节约很多dynamic mesh的资源。
如果想快速测试一下IB Method，可以考虑使用LS Dyna.
Netgen也很好用

个人经验是Netgen+Gmsh
