DirectMesh是一个Rhinoceros插件，故您需要首先安装Rhinoceros(最新版Rhinoceros 7.0或更高)。之后，请运行DirectMesh.rhi来安装DirectMesh到当前计算机。在安装之后，DirectMesh会自动授权当前计算7天使用权。在当前计算机授权到期后，您可以使用DBuy命令来购买OrderID并使用DAuthorize命令来授权当前计算机更多的使用时间。若想查询当前计算机剩余的授权天数，请使用DCheck命令。您还可以使用DOrder命令来查询绑定在给定E-Mail地址上的OrderID。想获取最新版DirectMesh，请使用DUpdate命令。有问题请联系许博士（电话：+86-15927279709，QQ：2650616297），我们的QQ群是：745410771。
DirectMesh is a plugin for Rhinoceros, which means you need to install the Rhinoceros first (latest version of Rhinoceros 7.0 or higher). After that, just run DirectMesh.rhi to install DirectMesh to the current computer . After installation, DirectMesh will automatically authorize the current computer 7 days of use. After the autorization of the current computer is expired, you can use the DBuy command to buy and an OrderID and then use the DAuthorize command to authorize the current computer more days of use. To check how many authorized days left of the current computer, please use the DCheck command. And you can check the OrderIDs of a given E-Mail address using the DOrder command. To get the latest version of DirectMesh, please use the DUpdate command. Contact Dr. Xu (tel: +86-15927279709, QQ: 2650616297) if you have any question. Our QQ-Group: 745410771.

在安装之后，下图所示界面会在您下次启动Rhinoceros时显示。
After the installation, the UI in the following figure will show up when you open Rhinoceros again.

若上述界面未能加载，你可根据下图手动加载。
If the above UI does not show up, you can mannually load it according to the following figure.

DirectMesh是一套用于在Rhinoceros建立网格及有限元模型的工具集，其包含如下功能：
DirectMesh is a set of tools to create meshes and finite element models using Rhinoceros, which has the following functions:

使用DirectMesh建立有限元模型的基本流程如下：
第1步，使用DMesh、DRepair、DMerge、DRemesh等命令在Rhinoceros中建立好有限元模型；
第2步，使用DBuild命令将网格模型建立为有限元模型；
第3步，在有限元软件中建立好有限元模型，并根据分组信息定义边界边界条件、荷载条件及单元材料。
The workflow of using DirectMesh to build finite element model is shown as follows:
Step 1, use commands such as DMesh、DRepair、DMerge、DRemesh to build the mesh model in Rhinoceros;
Step 2, use the DBuild command to generate the finite element model from the meshes;
Step 3, open the model in the finite element analysis software, and define the boundary conditions, load conditions and materials of elements.
