對話框是新建的，"resource.h"是隨對話框自動添加的，當然不會自動包含進某個.cpp或.h文件內，用到"resource.h"里定義的是新建的對話框類，是沒有包含"resource.h"的。將resource.h添加到stdafx.h或對話框類的頭文件中就OK了
STL頭文件要寫在VC6在CPP文件里生成的幾行代碼之前，謹記！有時除了直接引用該文件的頭文件和實現文件外，還需要檢查間接引用該文件的文件，是否#include在#ifdef _DEBUG之后
注意 1. webContent/WEB-INF的訪問權限不同。2.ServerLocations Use installation(middle) and Deploy use webapps. 3.新引入項目無法加載，新建工程復制其.settings and .project 兩個文件并修改

1. Modern Medicine Takes? Simulation to Heart
A fluid structure interaction simulation is performed to capture patient-specific modeling of hypertensive hemodynamics.

對血流動力學來說，工程設備的研究是其研究的關鍵，它可以受益于流固耦合的仿真模擬。集成了流體，結構，熱和電磁分析功能，所有這些功能可以為人們提供一種更好的認知方式，對了解心血管設備如何在人身體內運行是有較大幫助的。同時，這些分析可以為怎樣阻止這些設備產生的副作用提供有效的評估。
ANSYS軟件收集到可導致血栓形成的血液凝塊的重要信息。另一個例子是，在血管成形術手術中使用血管內支架技術可能會產生成血管再狹窄的危險，如果產生炎癥則可能會導致血管的再次狹窄甚至血管不在流通。利用ANSYS仿真軟件，醫療專業人士能夠確定在這個手術過程中動脈壁上的應力分布，然后優化血管內支架的設計，以盡量減少整個手術過程的風險性。

ANSYS FSI?
A CAD system is used to turn this skeletal data into a smooth? representation of the vessel geometry.
The geometry is imported into ANSYS ICEM CFD software and the Hexa meshing module is used to construct a high-quality hexahedral volume mesh.
The resulting mesh uses an O-grid inflation layer from all walls so that the mesh is nearly orthogonal with excellent control over near-wall spacing.This mesh is used for the CFD component of the FSI simulation, solved using ANSYS CFX software.The quad surface elements from that same mesh are imported into ANSYS as a shell element representation of the vessel. This type of representation is a significant advantage, since it allows investigations in which the vessel wall thickness is varied without the need for geometry modifications or remeshing. A script is used to apply variable shell thickness on a node-by-node basis to the vessel mesh.
For these studies the Arruda–Boyce hyperelastic material model is used. The model parameters were suggested by biomechanical studies of the stress–strain properties of normotensive and hypertensive pulmonary arteries from a rat model and solid-only simulations of human pulmonary arteries. Residual stress is not considered here due to the difficulty of incorporating such effects in clinical models in which direct measur ements within the artery cannot be obtained. The solid model was constrained on the inflow/outflow boundaries. The remaining nodes were allowed to deform in response to applied forces.

Blood is modeled as an incompressible Newtonian fluid with constant dynamic viscosity and the flow is assumed to be laminar. Using the CFX Expression Language (CEL), it was straightforward to implement a time-varying mass flow boundary condition at the fluid inlet with a half-sinusoid profile. Exit boundary conditions were modeled using CEL and a resistive relationship in which the outlet pressure for each branch was determined by multiplying the local instantaneous flow rate by a r esistance factor.
The early results of this pilot study have confirmed the anticipated behavior of the system. Upcoming studies with improved clinical and imaging data will allow validation and refinement of the simulation methodology. Eventually, the clinical use of non-invasive, patient-specific simulation may provide better under-standing of the progression of PAH and improved predictions of the potential outcomes of available treatments.
2. Designing? with? Heart
CFD-based design optimization for a miniature ventricular assist implant can shave years off the medical device development cycle
3.Expanding Stent Knowledge
Simulation provides the medical industry with a closer look at stent procedures.

Multiphysics: fully integrated two-way fluid structure interaction including moving/deforming domains; electromagnetic; acoustic
Fluid Simulation Tools: gas/fluid flow analysis including flow in porous media; chemical and biological agents transport; heat transfer; multiphase flow
?
These surfaces are imported into meshing software from ANSYS and meshed using the hex-core approach.? The team then used ANSYS? FLUENT technology to model blood flow in the connection region.
?
For example, one could examine the effect of changes in? wall geometry to predict the overall flow pattern and energy loss
